What are bearing pulllers

They have legs which circle around the back or inside of a part, and a forcing screw which centres up against the end of the shaft. As the forcing screw is tightened, the arms pull the part towards the end of the shaft.

A bearing is a part of a machine (such as an engine) that compels relative motion. Put simply, this means that a bearing rotates at the same speed as the rotating component; this helps to reduce friction between the moving parts.

A gear is a wheel containing teeth that work with others to alter the relation between the speed of a driving mechanism (such as the engine of a vehicle) and the speed of the driven parts (the wheels).

A pulley is a grooved wheel attached to a crankshaft. The pulley is connected by a belt that directs power to all the systems in an engine.

This is a two legged bearing puller removing a pulley from a shaft.
