Inner Bearing Puller

The inner bearing puller is a professional mechanical maintenance tool, which is often used to disassemble bearings in various mechanical equipment. It is mainly composed of handles, pull rods, pull claws and other parts. Some models are also equipped with multiple pull claws of different sizes to adapt to bearings of different specifications.

The operating principle of the inner bearing puller is to rotate the handle to drive the pull rod and pull claw to generate tension, which acts on the inner ring of the bearing, so that the bearing is disengaged from the installation position. This design ensures that the disassembly force acts directly on the inner ring of the bearing, avoiding damage to the outer ring of the bearing and other parts, and protecting the integrity of the equipment.

In terms of application scenarios, the inner bearing puller is widely used in many fields such as automobiles, industrial equipment, and motors. For example, in automobile maintenance, it can be used to disassemble engine main bearing caps, gearbox gears and other parts; in industrial equipment maintenance, it can be used to disassemble bearings in motors, reducers and other equipment. Its small and portable features make it perform well in places where space is small or it is inconvenient to use large tools, greatly improving maintenance efficiency.

The material of the inner bearing puller is usually high-strength alloy steel. After special heat treatment, it has good wear resistance and toughness. It can work stably under high load and has a long service life.
