The bearing puller is specifically designed for the task of removing bearings from shafts or housings. It consists of a central bolt, arms that grasp the bearing, and a mechanism for applying force in a controlled manner to pull the bearing off without causing damage to either the bearing itself or the components surrounding it. The design of a bearing puller allows it to effectively grip the bearing and apply even pressure, ensuring that the removal is smooth and safe, which is crucial in millwright operations where precision and equipment integrity are paramount.

While a puller tool may refer to any tool used for pulling objects, and other tools like heat guns can be employed to expand metal or facilitate bearing removal by applying heat, they are not specifically intended for bearing extraction like a dedicated bearing puller. Wrenches, meanwhile, serve primarily for fastening and turning nuts and bolts, and do not possess the specialized design needed for safely and efficiently removing bearings.
