Bearing Puller Types

Bearing Puller Types

Bearing pullers are a device used to remove a set of bearings from a rotating machine’s shaft or from a hole for a blind bearing. The most popular use is to remove an enclosed set of tapered or ball bearings from a rotating shaft, for example, in the transmission of a car. The tools are made from quality steel used for tooling, meaning they are more durable than the components used.

They typically operate by hand using a handle attached to the screw that turns, or the male hex end is used to match the drive socket. Some of them are hydro-powered, with an engine that is hydraulically powered to push against the shaft’s edge the bearing is mounted on.

What are Bearing Pullers?


Bearing pullers are an incredibly useful tool in any mechanist’s arsenal. Used to extract bearings, which are crucial components of many machines, these heavy-duty tools are available in various sizes and shapes for every potential application.

An amazing piece of technology, bearing pullers use carefully designed claws or hooks to grab the bearing from its placement and gently loosen it from its mount. This allows for easy installation – or removal – when required during maintenance work. Incredibly, even more incredible, these pullers usually don’t damage the base material due to their extreme dexterity and pinpoint accuracy. Bearing Pullers are one of the best tools available for anyone who works with machinery daily.

How to use a bearing puller?

Using a bearing puller can save time and energy if you ever have to remove a bearing from machinery. It works similarly to the common claw hammer in that it uses a specialized design to grip onto the edges of bearings.

To use one, clamp the puller onto the desired bearing and then use its lever system or screw mechanism to draw out the bearing slowly. This method is much quicker than cutting off the bearing or manually trying to pry it out and is also safer since you don’t risk damaging nearby parts in the process.

Plus, it’s surprisingly easy once you grasp the basic concept—keep your hands clear as you pull out parts!

Bearing Pullers: Types

1. Integral Bearing Puller, Split Type Bearing Puller

A hydraulically-integral bearing puller can be described as a single hydraulic puller with a built-in hand pump hydraulic.

A split-type puller consists of a hydraulic puller as well as an additional hydraulic pump; both parts are linked via High-pressure hydraulic pipes.

2. Hydraulic Bearing Puller and Mechanical Bearing Puller


The hydraulic puller utilizes fluid pressure to pull the bearing on the shaft. A mechanical bearing puller uses jaws that grasp the bearing and pull it off the shaft.

The type of puller you select is based on the size of the bearing and the one you’re removing. A hydraulic puller for bearings is generally utilized for larger bearings, while a mechanical puller is usually used for smaller sizes.

3. Trolley Mounted Bearing Puller

A trolley-mounted bearing puller is a device for pulling out bearings installed on a mobile trolley. The bearing puller is typically employed in industrial situations when heavy, and large bearings are required to be pulled from an assembly or shaft.

The trolley-mounted puller for bearings consists of a frame, which is supported by a hydraulic cylinder, and an arm attached to the puller’s head. The hydraulic cylinder is attached to the arm using pivot points, which lets the arm be elevated and lowered.

Its pulling arm is attached to one part of the arm and comes with various adapters that could be used to accommodate various dimensions and types of bearings. When the cylinder is activated the hydraulic cylinder pushes and pulls on the arm which then is pulled or pushed on the head that pulls it and removes the bearing from the mount.

4. Two Jaw Bearing Pullers and Three Jaw Bearing Pullers


There are several kinds of pullers for bearings in the marketplace. Two-jaws and three-jaw bearing pullers are the most popular.

The two-jaw puller for bearings is used to remove bearings having an inside diameter smaller than the size of the jaws pulling them. The three-jaw bearing puller can be utilized to remove bearings with an inner diameter greater than the size of the pulling jaws.

Bearing Pullers: What To Consider Before Buying

  • The first concern is the dimension of the bearing as well as its position. The pullers should be large enough to fit over the shaft and bearing. It is important to comprehend the spread and reach a distance of the puller before you make the purchase.

It is measured by the distance between the surface of the puller, that is, the jaw’s surface, and its jaw’s head. This distance changes and decreases as jaws expand. The spread is the width that jaws expand to. The typical range is 25 inches.

  • The other is the kind of puller. If space allows, it’s ideal to choose a 3-jaw puller instead of a 2-jaw because they are more secure and simpler to use. Hydraulic pullers are more user-friendly than mechanical pullers.

However, you’ll need an engine, hose, and gauge. Depending on the size of the puller, the pump can be operated by hand or electric.

  • The third factor is the weight that the puller can handle. Pullers can be found in a broad variety of capacities. Most models are between 2 to 50 tons.

Tips for using a bearing puller

Using a bearing puller can be a great way to save time and money, but it is essential to remember that proper technique is key to the best results.

To prevent damage to your parts, start by identifying the correct size of puller for your application and ensuring that it has been properly lubricated with the right type of oil.

Additionally, make sure to use the right amount of pressure and pay attention to which direction forces are being applied in order to keep your task safe and efficient.

Once you have done all this, you’ll find that using a bearing puller is a gratifying experience each and every time as you get professional-looking results without requiring too much effort!
