What is a bearing puller typically used for ? Application about puller set
A bearing puller is a tool used to remove bearing sets from a rotating machine shaft or from a blind bearing hole. The most common application is removing a caged set of ball or tapered bearings from a rotating shaft, such as in a car’s transmission. These tools are made of tool grade steel, so they are harder than the parts they are used on. They are usually hand-powered with a handle on the turn screw, or a male hex end to match a drive socket. Some bearing pullers are hydraulically powered, using a hydraulically powered piston to press against the end of the shaft the bearing is on.
There are also small-sized versions of bearing pullers to remove small millimeter-wide bearings in small fractional horsepower motors and fishing reels. There are arms with extensions that allow the user to pull in the inner race as well. It is preferable to drive from the inner race since it is firmly set on the shaft, while the outer race is not very well secured to the rest of the bearing assembly.
