What are the removal steps for the bearing retainer sleeve and pusher sleeve

1. When disassembling the fastening sleeve and withdrawal sleeve, apply grease to the threads on the fastening sleeve and withdrawal sleeve. Remove the nut and apply grease to the end face where the bearing contacts.

2. Inject high-pressure oil into the oil hole on the end face of the tightening sleeve or withdrawal sleeve with the hand oil pump. Under the action of high-pressure oil, forcefully rotate the disassembly nut or hydraulic nut to pressurize, so as to withdraw the tightening sleeve or withdrawal sleeve. (Removal of the fastening sleeve requires a threaded mounting nut at the shaft end as a fixing point.)

Removal of the sleeve bearing requires not only the use of a bearing remover, but also attention to some parts of the sleeve bearing for easy and simple removal. Failure to pay attention to these parts may also damage the bearing. The following are precautions for disassembling the bearing on the disassembly sleeve: When disassembling the bearing on the disassembly sleeve, the axial locking device, such as the locking nut and end cap, must be removed.

When disassembling small and medium-sized bearings, locking nuts and hook wrenches or impact wrenches can be used to loosen the bearings.

The best way to disassemble large bearings is to use hydraulic nuts. If the threaded portion of the shaft sleeve protrudes from the shaft end or shoulder, a support ring should be inserted into the sleeve hole, and the wall of the support ring should be as thick as possible to avoid causing thread deformation and damage when tightening the nut when using hydraulic pressure. It is recommended to add a barrier to the hydraulic nut end, such as through the shaft end. If the withdrawal sleeve suddenly separates from its shaft seat, a barrier can be used to prevent the withdrawal sleeve and hydraulic nut from completely withdrawing from the shaft.

The removal sleeve for large bearings is generally equipped with an oil distribution groove to facilitate the use of the oil injection method, greatly reducing the time required to install and disassemble large bearings.
