Bearing puller. Puller. Bearing. Types of pullers, description, purpose. An easy way to make a homemade pickup device

When repairing the steering and running gear, almost every car owner is faced with the problem of removing ball joints (tie rod ends), which is rather problematic to solve without a special tool.

Reason - design features of these elements: their fingers have a conical shape, with which they enter the landing sockets, over time, the place of this entry becomes dirty, oily, rusty, making the connection of the surfaces too tight, almost uniform, that is, one that cannot be separated by simple physical action. We need an assistant - a ball bearing puller - a tool that greatly simplifies pressing out.

It is not difficult to become its owner: to do this, you need to go to the nearest car shop and purchase it there or make a do-it-yourself ball joint puller using any of the methods below, which we have grouped depending on how force is created in them.

Screw pullers.

The force in these types of pullers is created by screwing the bolt into their body: the tool body is put on the eye of the ball joint, the bolt rests on the finger and, when twisted, presses it out of its seat.

These types of pullers are quite compact, therefore they are considered universal, that is, suitable for any car, although such mechanisms are most popular among VAZ owners.

Consider how to make a do-it-yourself ball bearing puller using examples of screw options.

Option number 1 - screw expanding.

1. Take a 7-centimeter 4- or 6-sided rod with turnkey edges of 17 or 19.
2. Using a drilling tank, make a hole inside its body and cut a thread for an M8 bolt.
3. Screw this bolt into the hole prepared for it. The puller is ready.

How it works, we will explain using the example of pressing out the upper ball joint of the "seven".

1. Unscrew the lock nut. We twist, but do not remove.
2. Between the fingers of the supports we install the made puller, the bolt in it is screwed up to the stop and rests with the cap on the finger that needs to be pressed out.
3. We take 2 keys: with one we hold the puller body, with the second we unwind its bolt. We unwind until the support pin is pressed out of the socket.

If it is necessary to dismantle the lower ball joint, all actions are done in the same way, only with the puller turned upside down.

Option number 2 - screw L-shaped.

1. Take a 15-17 cm round metal bar with a diameter of 10 mm or more. Using a vise and a hammer, bend it with the letter "G" (the length of the short arm should be 5 cm).
2. On the long arm of the workpiece, cut the thread and match the nut to it.
3. Take a metal plate half a centimeter thick and cut a hole in it for the support pin using the wedge puller technology (it will be shown below).
4. On the thickened part of the wedge, opposite the slot, make a hole for the L-shaped blank and thread the long part of the rod into it, only after that screw the nut onto the “improved” rod. Do not tighten too much - the wedge-shaped insert should have a good stroke.

1. Insert the plate into the gap between the eyelet and the support. The short arm of the L-shaped element should rest against the finger.
2. Start tightening the nut and do this until the finger is pressed out.

Option number 3 - a screw puller of ball bearings, made from a corner.

1. Take a 7-8 cm metal corner, half a centimeter thick, maybe a little less.
2. On one side, make a cut; with this cut, the tool will be attached to the eye.
3. From metal plates equal in thickness to the metal of the corner, cut out 2 identical triangles and weld them on the sides of the corner.
4. Take a 17 nut, pick up a long bolt to it, weld spacers to this nut on both sides, they will help to position the puller bolt on the same axis with the support pin in the future.

1. Screw the bolt into the fixed nut and wring out the finger using the technology described above (in other types of screw pullers).

As you can see, to create a ball joint puller, you can use almost all available materials, the main thing is to understand the principle of operation, a drawing will help you:

Lever pullers.

Lever pullers are a tool consisting of a pair of levers connected to each other in the middle. Also on the one hand they have a coupling bolt. In the process of acting on the ball joint, this bolt is unscrewed, bringing the ends of the levers together, one of which is located between the support and the lug, the second is under the finger.

Such pullers are also quite effective, but have larger size and therefore may not be applicable everywhere.

wedge type puller.

The simplest in its design, but it also copes well with the task assigned to it. To make it you will need:

• take a small metal plate (enough size for a matchbox);
• using a grinder (angle grinder) / machine with an abrasive wheel, give it the shape of a wedge, the resulting workpiece in profile should take the form of a triangle;
• with the same grinder, starting from the upper corner of the triangle, it is necessary to make a vertical cut in it 2/3 of its height, a little wider than the diameter of the ball joint pin;
• to facilitate working with the tool, it is recommended to weld a metal rod to the middle of the base of the wedge, although this may not be done if you do not have such a rod at hand.

Here is such a kind of bracket you should get in the end.

1. insert the wedge just made between the ball body and the eye;
2. hitting the rod (the base of the wedge) with a hammer, drive in the homemade support puller until the finger pops out of the socket.

IMPORTANT!

When using this type of puller, there is always a risk of damage to the anther, therefore, such a tool can only be used in the event of a planned replacement of tips or supports. If the repair of the steering mechanism or suspension does not provide for such a replacement, it is better to refuse a wedge-type puller.

Puller directly ball bearings.

It is used for cars (Citroen, Peugeot) whose ball joint is screwed into the lever. And since it is screwed in and not pressed in, it is not practical to use the above tool options, you need a special puller, which we suggest you make from 8 cm thick metal pipe on 2".

1. On one of the ends of this pipe, equidistant from each other, using a grinder or a hacksaw, make 4 rectangular spikes 5 × 7 mm.

1. On the second end, with the same tool, again, equidistant from each other to a depth of 3 cm, cut the slots so that in the end you get 8 petals.
2. With a hammer, slightly bend these petals towards the center of the circle, thereby reducing its diameter.

1. Take a 24mm nut and weld it to the tapered side of the workpiece. Do-it-yourself ball joint puller is ready.

It is easy to use: put it on the support so that the spikes enter the existing grooves of the ball body, then turn the welded nut with a 24 wrench, thereby dismantling the suspension element you need.

Such an element as a bearing is used in many units and mechanisms. It can also be found on the car. For example, this or a hub element. In any case, a puller is required to dismantle it. The bearing is very tight. It is extremely difficult to extract it with improvised means. Therefore, today we will consider what bearing pullers are, their dimensions and design features.

Device

The main element in the design of this element is the central bolt. It is due to him that the puller works. The bearing is thus squeezed out of the workplace or, conversely, pressed in (depending on which way to turn the central bolt). Some devices are equipped with a hydraulic cylinder (for example, bearings, as in the photo below).

Also in the design there are grips. They are of two varieties:

• Grippers that are engaged with the object to be retrieved using a special tool. They work independently of the action of the bolt.
• Pressing the part due to the force of the bolt or

The material from which the puller is made

The bearing is a part that is quite difficult to remove. Therefore, puller manufacturers use only high-strength alloyed materials. Responsible nodes in these elements are formed by forging. As for power bolts, they have a higher strength than those used in conventional threaded connections.

Kinds

There are several types of these tools. All of them differ in the type of capture. He can be:

• Sliding.
• Rotary.
• conical.
• With separator.
• Universal.

With regard to dimensions, the inner bearing puller can have a different diameter. On average - from 28 to 200 millimeters. The height of the foot is from 35 to 60 millimeters. Bolt head size - from 9 to 22 millimeters.

sliding puller

It is quite easy to remove the bearing with such a tool. Such a puller has two grippers that move freely along the beam. In the middle of the latter there is a threaded hole. In the upper part, the bolts can serve as clamps for the grips.

It can be a puller for internal bearings or external ones. To change its purpose, it is enough to rearrange the grips. By the way, their maximum solution is from 10 to 80 centimeters. The device has stops for a power bolt. This prevents the bearing from moving. The set of sliding pullers includes grippers of different lengths. Also the tool is completed with replaceable tips. Usually they have the same dimensions (they serve as a substitute in case of failure of the first element).

With swivel grips

They have different design. The grips are secured with bolts. For which vehicles is this bearing puller used? VAZ, MAZ, GAZ, Mercedes - this is an incomplete list of cars on which this tool can be used.

The puller has stops with double-sided grip. There are tools with a tripartite. There are 4 fixing points on the body of the device. Bearing pullers are installed on them. The grip width of the device is from 5 to 7 centimeters. Used to extract bearings small size, including for dismantling the tip of the battery wires. It can be equipped with a percussion mechanism.

With conical gripper

These tools have 3 jaws and are used in situations where it is required to eliminate load imbalance when dismounting a bearing. Often this type of hydraulic bearing puller is sold.

Centering of captures happens automatically. Also in the design there is a conical nut, which is manually wrapped when installing the tool. On some models it is spring loaded. It has a limited range of uses. Turning the clamps here will no longer work.

With separator

These tools are different high reliability. The element is based on a separator. It is installed under the removed bearing. Both halves of the cage are bolted together for a more secure grip. After that, the pulling part is connected to the tool.

Its side nuts are adjustable according to the position of the cage. The power bolt is driven onto the axis of the part to be removed. The tool can be used in combination with a sliding puller. However, when working with two mechanisms, it is required to monitor the safety of the bolt threads.

Universal

Pullers universal for bearings are used most often. They also extract other mechanisms. The design is based on a power bolt made of alloy steel. By rotating it, the master creates a dismantling force that is applied to the reference point. Through the central body of the tool, this force is transmitted to the clamps. Thus, the part is pulled out or pressed into place. Universal pullers are used for both internal and external bearings.

Price

The cost may vary depending on the type, as well as the set of tools that is included in the kit.

The cheapest are two- and three-jaw sliding pullers of a mechanical type. Their price ranges from 500 to 1 thousand rubles. Hydraulic devices are the most expensive. They are offered on the market at a price of 25 thousand rubles. The cost of universal mechanical solutions is around 10 thousand rubles. The kit includes a set of mandrels.

Options

To choose the right bearing puller, you need to know what parameters it must meet. When buying, you should pay attention to the following points:

• Maximum allowable load. This parameter is determined by the strength of the central body of the puller and the power bolt. At mechanical tools this parameter is from 1 to 4 tons. Hydraulic pullers have a force of about 20 tons (but they also have a corresponding price). However, for the dismantling of elements such as the hub bearing, mechanical tools are sufficient.
• Working move. It depends on the overhang of the power bolt and the length of the grips.
• The dimensions of the puller legs (in particular, the width and height of the stop).
• Minimum and maximum grip opening.

Primitive do-it-yourself puller

This tool can be made independently. A steel pipe is used as the main element. Its diameter should be slightly larger than that of the clip. So, with the help of a grinder, we cut off a piece of pipe of the desired length. It depends on the size of the screw. Next, by welding, we connect the C-shaped washer to the cut out part of the pipe. On the other hand, a nut is welded with internal thread. It must match the parameters of your screw. This type of puller is the easiest to manufacture. However, it will only fit a specific bearing diameter.

Making a universal tool

Such a puller will fit different diameter elements. So, we need to make paws from a 10 mm steel sheet. It is better to use pre-prepared templates. They can be made on cardboard or paper, then marked on a metal sheet and cut out with a grinder.

Then you need to pick up the bolt. We sharpen it under a cone. Six lugs with holes are welded to the nut. Our paws will be attached to the latter. Ears are cut out of metal with a thickness of 5 millimeters. The ears are welded to the nut in assembled form. Next, the bolts are unscrewed and the joints of the legs are finally welded. At this stage, the assembly of the device is completed. You can begin to fully use the tool.

Conclusion

So, we found out what types of pullers for bearings are. The most common types are universal solutions of the mechanical type. They can be used to extract any bearings and pulleys. Puller - highly useful thing in the economy. Especially if you own a car. With this tool, you can even perform such a complex operation as replacing a wheel bearing. In services, the cost of this service is from 3 thousand rubles.

Very cool and useful item. Puller for bearings. Useful pipe, iron plate, large washer, bolt, nut.

To begin with, we mark on the pipe the size that needs to be sawn off. Weld the washer to the resulting segment. We put the nut exactly on the hole and weld it. Let's clean the bumps with a grinder.
Measure 1.5 centimeters, make a cut. On the other hand, it's the same. Cut off two small pieces from the plate. They will be inserted into two slots. Got a puller.

How does this tool work? We put on a bearing. We go behind him two records. We turn the bolt. It rests on the shaft and pulls the bearing off it. With this tool, you can easily remove it from the generator and electric motor. The outer diameter of the part must not exceed the inner diameter of the pipe.

Second idea

Airat Valiakhmetov, the host of the eponymous channel on youtube, developed his own original idea. In the store, such tools are not cheap. So I decided to do it myself. I took a metal strip 30 wide, 4 mm thick. Cut it into strips. Welded. Plates. Hooks to grip the bearing. Two cuts are made with a grinder. Two nuts are inserted and welded on. I took the worm from an old Soviet clamp. Hardened steel. To make the tool universal, I made 4 holes on each side. Can be set to any width. If necessary, the paws are pulled out, turned over to the other side. You can pull out the bearing.

How to understand that the wheel bearing is out of order? By sound! The main symptom is a hum that gets worse with acceleration. If it occurs only occasionally, then the bearing has just begun to break. A constant suspicious sound with increasing load means that this part of the car requires immediate replacement. In any case, you will need a bearing puller to carry out repairs. You can buy it or make it yourself.

How a puller makes life easier for a car owner

Using this tool, you can dismantle bearings, bushings, pulleys, flanges and other components, remove or fix rings and gears, and repair chassis elements. It greatly simplifies the process Maintenance and repair of various parts of the vehicle. Using the right puller, you can quickly and easily replace a damaged element without risk of damaging the machine elements connected to it. In addition, the tool can be used to work on hard-to-reach parts of the car, in a convenient position.

Products can have a different design, but the most common is the following - several gripping paws, which are in the form of hooks, and a threaded rod between them. Thanks to this structure, you can easily grab the required element and press the bearing out of it.

Kinds

The tools are divided into two groups.

• Hydraulic. During their work, hydraulic traction is used, the removal and landing are carried out in a semi-automatic mode. The main part of such a puller is a hydraulic nut, the inner cavity of which presses on a special piston. That, in turn, transfers the force to the desired part. The hydraulic model is in demand among owners of trucks and other large vehicles - with its help, you can easily remove the most massive internal parts.

This is what a hydraulic bearing puller looks like

• Mechanical. They operate from the muscular strength of a person, they are in demand for the installation / dismantling of wheel bearings. There are two-grip, three-grip and internal. Double grip - the simplest. They are used where maximum process control is needed. Three-jaws are equipped with three paws and are used to work with the front hub and generator. Internal options useful for removing ball and needle roller bearings, in addition, they can be used to dismantle various brass couplings.

Mechanical 3-jaw model

Bearing pullers may have different sizes, but the most popular are universal. Their parameters can be adjusted manually, adjusting to any diameter.

You can make different tools with your own hands, but it is best to make a universal three-grip version - it is convenient to use.

Scheme of a two-jaw puller

We make a universal three-armor with our own hands

To make a universal three-jaw puller designed to work with bearings ranging in size from 202 to 308, you will need:

• sheet metal (10 mm wide);
• metal-round timber with a diameter of 30 mm.

If you plan to remove large bearings, take sheet metal 15 mm wide and round timber 30 mm in diameter.

An easy way to make a homemade pickup device

This option is easier to perform, but the product will not be so convenient. You will need the following tools and materials:

• steel pipe, the inner diameter of which will be larger than the diameter of the bearing;
• metal plate with a thickness of more than 5 mm;
• Bulgarian;
• a stud with a nut or a bolt with a long thread;
• a few nuts.

1. Cut off a piece of pipe of the desired parameters.

   Cut off part of the pipe

2. We mark all the necessary elements on a metal sheet, circle the pipe and the bearing.

   Laying out future details

3. We cut out the details with a grinder, grind them to match the exact parameters.

   Cut out details

4. We drill holes for the bolt in the resulting washers.

   Drilling holes for bolts

A must have for every true master. Sometimes there is a need to repair power tools, and namely, the replacement of bearings, which wear out sooner or later. If you remove the bearing with a hammer, screwdrivers and other not very suitable solutions, there is a risk of damaging the axle, threads or individual nodes on the axle, more often it happens. And sometimes the bearing sits on the axle so firmly that it can be removed far and not by every puller.

In this tutorial, you will learn how to make a simple, powerful puller that will always help you out in a difficult situation. To assemble it, you will need a piece of thick-walled pipe and a thick steel plate. If you wish, you can make yourself several pieces of such pullers for products various sizes. Consider in order how to make such a device.

Materials and tools used
List of materials:
- thick-walled pipe;
- thick steel plate;
- bolt and nut (larger);
- a metal rod (a handle is made from it);
- dye.

List of tools:
- ;
- (cutting disc, metal brush, as well as a grinding disc);
- a drill with large bits or a drilling machine;
- lathe, cutting machine(not necessary).

Puller manufacturing process:

Step one. Preparing the main part
A piece of thick-walled steel pipe acts as the main part of the puller, it works like a frame. If the pipe is not strong enough, and the loads are large. It can easily be bent. The wall thickness of the pipe must be at least 3 mm.

We cut off the desired piece from the pipe, the author uses a cutting machine for this, but everything can be done with a grinder. Now the most difficult part begins, you need to cut a window in the pipe. This can be done with the help of a grinder, it is long, but quite feasible.

Step two. We make the upper and lower supports
For the upper support, the author decided to use the thickest possible sheet steel. Cut out the circle desired diameter. The author uses a grinder for work, first we cut out the “polygon”, and then with the help of a grinding wheel we bring it to the ideal.

Cut out the other circle in the same way. Here the author used a slightly thinner steel, but it’s better not to risk it, since the loads on both supports are approximately the same.

In the end, you need to modify the supports. Drill a hole for the bolt in the top support. First, we drill a small hole with a drill, and then ream it to the desired diameter. The author used a lathe for these purposes.

As for the lower support, we also drill a hole in the center in it, in diameter it should be slightly larger than the diameter of the axles from which you are thinking of removing the bearings. Then cut a triangle shape to this hole. Supports are ready, let's move on!

Step three. Welding
In this step, we need to weld both supports to the body. The welding seam must be good, reliable, we set more current so that the metal melts well.

Having welded the supports, now you need to fix the nut. We wrap the bolt in it and insert it into the hole. We weld the nut well, but try not to overheat, as the metal can become soft. The author attaches the nut from above, but I would recommend attaching it from the inside, so it will rest on the support, and the tear weld may not be too reliable.

At the end, you will have to fix the handle, for this the author used a threaded rod. Using the handle will be convenient to remove bearings that are not too tight. Otherwise you can always use wrench.

Step four. Completion and testing
When you complete the welding work, you need to clean the welds, but this is more of an aesthetic moment, there is little practical use here. The author cleans the slag with a wire brush, and cleans the seams with a grinding disc. The whole body can be brought to a shine. Now paint homemadeso that the metal does not rust.

Finally, sharpen the end of the bolt so that it rests when twisting into the "hole" provided on any axis. Also, remember to lubricate the threads well so that the puller works easily and for a long time.
