Mechanical pullers are used to remove or replace bearings, pulleys couplings and other parts that fit closely together. They are most commonly used to remove tapered bearings from a rotating shaft, such as in a car's transmission.
Mechanical pullers are important as they can remove the bearings and pulleys etc. without the need to dismantle machinery or remove the running shaft.
Mechanical pullers have claws and a centre forcing screw which allows them to remove the parts easily. They are available with two or three arms:
There are also slide hammer-style mechanical pullers which are used for extracting ball bearings in tight or confined spaces where it is not possible to use a standard puller, and grip clamp extractors for high-power extraction when removing gear wheels or magnetic flywheels.
