Taper bearing puller. Puller. Bearing. Puller types, description, purpose. A simple way to make a homemade pickup device

Carrying out repairs to the steering and chassis, almost every car owner is faced with the problem of removing the ball joints (steering rod ends), which is rather problematic to solve without a special tool.

Reason - design features of the named elements: their fingers have a cone-shaped shape, with which they enter the landing nests, over time, the place of this entry becomes dirty, oily, rusts, making the connection of surfaces too dense, practically unified, that is, one that cannot be separated by simple physical action. We need an assistant - a ball joint 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 auto store and buy it there, or make a puller for ball joints with your own hands using any of the methods presented below, which we have grouped depending on how an effort 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 eyelet of the ball joint, the bolt rests on the finger and, when screwed, 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 owners of VAZs.

Let's consider how to make a do-it-yourself ball joint puller using examples of screw options.

Option number 1 - screw expanding.

1. Take a 7-centimeter 4-or 6-sided rod with 17 or 19 flanks.
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 by the example of pressing out the upper ball joint "seven".

1. We unscrew the lock nut. We unscrew, but do not remove.
2. We install a made puller between the fingers of the supports, the bolt in it is screwed in until it stops and rests with the head against the finger that needs to be pressed out.
3. We take 2 keys: with one we hold the puller body, with the second we unscrew its bolt. We untwist until the support pin is pressed out of the socket.

If it is necessary to dismantle the lower ball, all actions are done in the same way, only with an inverted puller.

Option number 2 - screw L-shaped.

1. Take a 15-17 cm round metal rod 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 shoulder should be equal to 5 cm).
2. On the long arm of the workpiece, cut a thread and select a nut for 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 given below).
4. On the thickened part of the wedge, opposite the notch, make a hole for the L-shaped workpiece and insert 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 plate should move well.

1. Insert the plate into the slot between the eyelet and the support. In this case, the short shoulder of the L-shaped element should rest against the finger.
2. Begin to tighten the nut and do this until the finger is extruded.

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

1. Take a 7-8-centimeter metal corner, half a centimeter thick, or a little less.
2. Make a cut on one side, with this cut the tool will be attached to the eyelet.
3. Cut 2 identical triangles from metal plates equal in thickness to the metal of the corner and weld them on the sides of the corner.
4. Take a nut for 17, pick up a long bolt for it, weld the spacer to this nut on both sides, in the future they will help to position the puller bolt on the same axis with the support pin.

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

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

Lever pullers.

Lever pullers are a tool consisting of a pair of levers interconnected in the middle. They also have a tightening bolt on one side. In the process of acting on the ball joint, this bolt is unscrewed, bringing together the ends of the levers, one of which is located between the support and the eyelet, the second - under the finger.

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

Wedge-type stripper.

The simplest in its design, however, 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 to give it the shape of a wedge, the resulting workpiece in profile should take the shape of a triangle;
• with the same grinder, starting from the upper corner of the triangle, you need to make a vertical cut in it by 2/3 of its height, with a width slightly larger than the diameter of the ball finger;
• to make it easier to work 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 brace you should end up with.

1. insert the wedge just made between the ball body and the lug;
2. hitting the rod (base of the wedge) with a hammer, hammer 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 boot, therefore, such a tool can be used only in case 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 puller.

Ball joint puller directly.

Used for cars (Citroen, Peugeot) spherical bearing which are screwed into the lever. And since it is screwed in, and not pressed in, it is impractical to use the above tool options, you need a special puller, which we suggest you make from an 8-centimeter thick metal pipe on 2".

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

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

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

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

An element such as a bearing is used in many assemblies and mechanisms. It can also be found in a car. For example, this is either a hub element. In any case, a puller is required to remove it. The bearing is very tight. It is extremely difficult to extract it with improvised means. Therefore, today we will consider what kind of bearing pullers are, their sizes and design features.

Device

The main element in the construction of this element is the center 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 direction to turn the central bolt). Some devices are equipped with a hydraulic cylinder (for example, bearings, as in the photo below).

There are also grips in the design. They come in two varieties:

• Grips that engage with the retrieved object using a special tool. They work independently of the bolt action.
• Pressing the part due to the force of the bolt or

The material from which the stripper is made

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

Views

There are several types of these tools. They all differ in the type of capture. He might be:

• Sliding.
• Swivel.
• Conical.
• With a separator.
• Universal.

In terms of dimensions, the inner bearing puller can be of different diameters. On average - from 28 to 200 millimeters. The height of the foot is 35 to 60 millimeters. The size of the bolt head is from 9 to 22 millimeters.

Sliding puller

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

It can be an internal bearing puller or an external one. To change its purpose, it is enough to rearrange the grippers. By the way, their maximum solution is from 10 to 80 centimeters. The device has stops for the power bolt. This prevents the bearing from moving. The set of sliding strippers includes jaws 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 arms

They have different design... The grips are locked 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 a double-sided grip. There are tools with a three-sided one. There are 4 attachment points on the body of the device. They are fitted with bearing puller legs. The grip width of the device is from 5 to 7 centimeters. Used to retrieve bearings small size, including for dismantling the tip of the battery cables. Can be equipped with an impact mechanism.

With tapered jaws

These tools have 3 grips and are used in situations where it is required to eliminate unbalanced loads when removing the bearing. A hydraulic bearing puller is often sold of this type.

The centering of the grippers is automatic. Also in the design there is a tapered nut, which is manually tightened when installing the tool. On some models it is spring loaded. Has a limited range of uses. You won't be able to flip the clamps here.

With separator

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

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

Universal

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

Price

Cost may vary by type as well as the set of tools included in the kit.

The cheapest are two- and three-arm mechanical sliding pullers. 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 permissible load. This parameter is determined by the strength of the central body of the stripper and the power bolt. Have mechanical tools this parameter ranges from 1 to 4 tons. Hydraulic pullers have a force of about 20 tons (but their price is appropriate). However, mechanical tools are sufficient to dismantle items such as the hub bearing.
• Working stroke. It depends on the reach of the power bolt and the length of the grippers.
• Puller arm dimensions (in particular, width and height of the stop).
• Minimum and maximum grip opening.

DIY primitive puller

This tool can be made by yourself. 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 required length. It depends on the size of the screw. Next, using 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 should match the parameters of your screw. This type of puller is the easiest to manufacture. However, it will only fit the specific bearing diameter.

Making a universal tool

Such a puller will fit different element diameters. So, we need to make the legs from a 10 mm sheet of steel. 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 the cone. Six lugs with holes are welded to the nut. In the latter, our legs will be attached. The ears are cut from metal 5 millimeters thick. The ears are welded to the assembled nut. Next, the bolts are unscrewed and the joints of the legs are finally boiled. At this stage, the assembly of the device is complete. You can start making full use of the tool.

Conclusion

So, we found out what types of bearing pullers are. The most common types are mechanical type universal solutions. They can be used to remove any bearings and pulleys. The stripper is very useful thing on the farm. Especially if you own a car. Even such a complex operation as replacing a wheel bearing can be performed with this tool. In services, the cost of this service is from 3 thousand rubles.

A very cool and useful thing. Bearing puller. Useful pipe, iron plate, large washer, bolt, nut.

First, mark the size on the pipe that you want to saw off. Weld the washer to the obtained segment. Put the nut exactly on the hole and weld it. Let's clean the irregularities with a grinder.
Measure 1.5 centimeters, make a cut. On the other hand, the same thing. Cut two small pieces from the plate. They will be inserted into two slots. The result is a puller.

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

Second idea

Ayrat Valiakhmetov - the host of the channel of the same name on youtube has developed his original idea... In the store, such tools are not cheap. So I decided to do it myself. I took a metal strip 30 mm wide and 4 mm thick. Cut it into strips. Cooked. Plates. Hooks to grip the bearing. Two cuts are made with a grinder. Two nuts inserted, welded. He took the worm from an old Soviet clamp. Tempered 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 do you know if a wheel bearing is out of order? By the sound! The main symptom is the hum, which intensifies during acceleration. If it occurs only occasionally, then the bearing has just begun to break. A constant suspicious sound when the load increases means that this part of the car needs to be replaced immediately. In any case, you will need a bearing puller to carry out repairs. You can buy it or do it yourself.

How a puller makes life easier for a car owner

Using this tool, you can dismantle bearings, bushings, pulleys, flanges and other assemblies, remove or fix rings and gears, and repair chassis elements. It greatly facilitates the process. maintenance and repair of various parts of the vehicle. By using the correct puller, you can quickly and easily replace a damaged element without the risk of damaging the connected machine elements. In addition, the tool can be used to work with hard-to-reach auto parts in a convenient position.

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

The instruments are divided into two groups.

• Hydraulic. During their operation, hydraulic traction is used, removal and landing are performed 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 effort to the desired part. The hydraulic model is in demand among owners of trucks and other large-sized vehicles - with its help you can easily remove the most massive internal parts.

This is what a hydraulic bearing puller looks like

• Mechanical. They act on the muscular strength of a person, they are in demand for mounting / dismounting wheel bearings. There are two-gripping, three-gripping and internal. Two-grip are the simplest. They are used wherever maximum process control is needed. Three-gripping arms are equipped with three legs and are used for working 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 three-grip model

Bearing pullers may have different sizesbut the most popular are the universal ones. 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.

Two-grip puller diagram

We make a universal three-grabber with our own hands

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

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

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

A simple way to make a homemade pickup device

This option is simpler in execution, 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 greater than the bearing diameter;
• metal plate more than 5 mm thick;
• 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 required parameters.

   Cut off part of the pipe

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

   Marking up future details

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

   Cut parts

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

   Drilling holes for bolts

Every real master must have it. Sometimes there is a need to repair power tools, namely, to replace bearings, which sooner or later wear out. 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 assemblies on the axle, more often it happens. And sometimes the bearing sits on the axle so firmly that it turns out to 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 difficult situations. To assemble it, you 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. different sizes... Let's 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);
- paint.

Tool list:
- ;
- (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 as a frame. If the pipe is not strong enough, and the loads are large. It can be easily bent. The pipe wall thickness 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 hardest part begins, you need to cut a window in the pipe. This can be done with 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 sheet steel possible. Cut out the circle required diameter... The author uses a grinder for work, first we cut out a "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 steel a little thinner, but it is better not to risk this, since the loads on both supports are approximately the same.

Finally, you need to modify the supports. A bolt hole must be drilled in the upper support. First, we drill a small hole with a drill, and then we drill it to the desired diameter. The author used a lathe for these purposes.

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

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

Having welded the supports, now you need to fix the nut. We wrap a 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 very reliable.

In the end, you just need to fix the handle, for this the author used a threaded rod. With the help of the handle it will be convenient to remove bearings that are not too rigid. Otherwise, you can always use wrench.

Step four. Completion and test
When the welding work is completed, you need to clean up the welds, but this is more of a moment of aesthetics, there is little practical use. The author removes the slag with a wire brush and cleans the seams with a grinding disc. The entire body can be brushed. Now paint the homemade product so the metal doesn't rust.

Finally, sharpen the end of the bolt so that it rests when screwing into the "hole" provided on any axis. Also, be sure to lubricate the threads well to keep the puller running smoothly and easily.
