SKF bearing pullers are available in a wide range of types for drawing: pull-out, pull-up, and even blind pull. Puller types include mechanical pullers, hydraulic pullers and hydraulic auxiliary pullers for easy drawing. Bearing pullers are devices that take the inner bearing out of the bearing housing. The inner bearing puller comprises a mounting plate, a tension bolt and a wire bolt; there are no less than two tension bolts, and each of the tension bolts has a claw at the bottom of the inner bearing that can be hung on the bottom of the inner bearing, at each pulling force A fastening nut is mounted on the bolt, and there is no less than one long hole in the middle of the mounting plate. The width of the long hole is larger than the diameter of the tension bolt, and the lower end of each tension bolt passes through the long hole and extends below the mounting plate. The fastening nut can be caught on the mounting plate at the long hole; at least two positioning nuts are fixed on the mounting plate outside the long hole.
