Types of Bearing Pullers Explained

External bearing pullers are designed to grip the outside diameter of a bearing mounted on a shaft. These tools typically feature two or three adjustable arms that fit behind the bearing, and a central forcing screw that applies pressure against the shaft end to extract the bearing smoothly. Two‑jaw pullers are compact and suitable for smaller jobs, while three‑jaw pullers provide more even force distribution and better stability for larger or stubborn components. 

Internal or blind bearing pullers are used when the bearing is seated inside a housing or recess where the outer diameter is not accessible. These pullers have jaws or collets that expand inside the bearing’s inner race to grip it securely, allowing technicians to pull the bearing outward without external access. This type is especially useful for bearings in engine blocks or housings where space is limited. 

Reversible bearing pullers offer flexibility by allowing the same tool to be configured for either external or internal pulling. The legs or jaws can be flipped or adjusted to grip from the outside or expand inside the bearing’s inner diameter. This versatility makes them valuable in workshops that handle a range of bearing locations and sizes. 

Hydraulic bearing pullers use hydraulic pressure to generate high pulling force with minimal manual effort. These tools are ideal for large bearings and heavy‑duty applications where standard manual pullers may struggle. Hydraulic models can be designed as external or internal pullers and provide controlled force that reduces the risk of damage while improving efficiency in demanding repair tasks. 

Slide hammer bearing pullers attach to a bearing and use an impact‑style pulling motion to extract the component. The slide hammer generates repeated shock force along the tool’s axis, making it effective for removing bearings that are corroded or stuck. This type of puller works well in situations where space is tight and traditional screw force may be challenging to apply.

Bearing separators, also known as splitters, are specialized tools used when there is limited space between the bearing and adjacent components. These tools fit behind the bearing and create a wedge that allows a puller or press to remove the bearing without contacting the outer race directly. They are particularly useful for bearings that are tightly fitted in housings or against other parts.
