A bearing puller is a tool specifically designed to remove or install bearings from rotating machine shafts or from blind bearing holes. Dependant on the size of the puller, the application can vary dramatically, ranging from transmission to complicated industry machinery.
Where can a Bearing Puller be used?
One of the main uses of a bearing puller in within a car, removing a caged set of ball and tapered bearings from a rotary shaft. Different types of bearing pullers will depend on the application they are used for: •Hydraulic pullers – are designed to pull any bearing, belt pulley, gear, round wheel or other tightened part used within the machinery industry. One of the main features of using a hydraulic version is that the job of removing or dismounting a bearing is much simpler, faster and safer. •Strong back pullers – are used for easy insertion between bearing and shoulders on a shaft, featuring a spring operated centre point and a safety valve, minimising puller overload. •Heavy-duty jaw pullers – are considered the most versatile, they offer easy and effective dismount of bearings. They offer minimal damage to a bearing, through the use of a jaw, the whole operation is of pulling a bearing is easy and safe. Jaws are commonly used in industrial and commercial environments. •Internal bearing pullers – can be used for removing grooved ball bearings efficiently from shafts and cases without dismounting a bearing. This is known as a user friendly option because some gear puller sets feature an elastic retaining ring which helps keep the puller arm in position.
How Bearing Pullers work
Usually a hand powered tool or tool kit that features a handle on the turn screw, or a male hex end to match a drive socket. There are mechanical pullet sets, hydraulic puller sets, gear puller sets and standard bearing pullers available that mimic the same actions of the hand powered gear puller.
Features of a Puller Kit
Pullers are often made from tool grade steel, which means that they are harder than the materials that they are being used on. This ensures that they do not break when they are pulling bearings. •Reversible for internal or external uses •Two or three claw design •Spring loaded centre point
