A deep groove ball bearing puller is a tool used to remove deep groove ball bearings from a shaft or housing without causing damage to the bearing or the mounting surface. It typically consists of two arms that are placed around the bearing, and a center screw that is turned to apply pressure and pull the bearing out of its housing.

There are different types of deep groove ball bearing pullers available in the market, including manual pullers and hydraulic pullers. Manual pullers require physical effort to apply pressure to the center screw, while hydraulic pullers use hydraulic pressure to create force and remove the bearing.

It is important to choose the right size and type of puller for the bearing being removed, as using an incorrect or improperly sized puller can cause damage to the bearing, the mounting surface, or the puller itself. It is also important to follow the manufacturer's instructions and safety precautions when using a deep groove ball bearing puller.
