Demolition Withdrawal sleeve bearings, the axial locking device must be: lock nut, cap, etc.
Removal of small and medium-sized bearings, you can use the locking nut and hook wrench or impact wrench to loosen the bearing.
The best way to remove large bearing is with hydraulic nuts. If the threaded portion of the sleeve shaft or shaft protruding from the shoulder, should be supported in the sleeve insert hole ring, support ring wall should be thick, so when the use of hydraulic pressure, so that when you tighten the nut thread deformation damage. Recommended hydraulic nut end with a blocking material, such as through shaft. If the withdrawal sleeve shaft seat with a sudden separation barrier material can be used to avoid withdrawal sleeves and hydraulic nut completely Withdrawal from the axis.
For large bearings with withdrawal sleeve is generally equipped with tubing slots to use oil injection method, greatly reducing the installation and removal of the time required for large bearings.
