GSH Bearing Adapter Sleeve Mounting

GSH Bearing Adapter Sleeve Mounting Guide

Applicable for: Radial insert ball bearings with integral adapter sleeve

1. Preparation

   • The bearing seats on the shaft and the outside surface of the adapter sleeve must be dry and free of grease.

   • Push the housing unit onto the shaft and align it with the fixing holes in the adjacent construction.

2. Securing the Housing

   • Bolt the housing to the adjacent construction using the appropriate fixing screws.

   • If the shaft is supported by several housing units:

     1. Tighten the screws finger-tight only.

     2. Carefully align the shaft to ensure it is straight.

     3. Finally, tighten the screws securely to the recommended torque.

3. Tightening the Locknut

   • Tighten the locknut using two hook wrenches, type A according to DIN 1810.

   • The adapter sleeve must be held in place with the second wrench during tightening.

   • Refer to the table below for the correct wrench size and maximum tightening torque (MA).

   • ⚠️ Do not exceed the specified tightening torque MA; otherwise, the operating clearance in the bearing will become too small.

   • Note: Tightening the locknut will slightly displace the bearing in an axial direction.

4. Securing the Locknut

   • Bend the tab of the tab washer into a groove of the locknut to prevent loosening.

   • ⚠️ The seal of the bearing must not be damaged when bending the locking tab.

5. Dismounting

   • Bend back the tab of the tab washer.

   • Loosen the locknut a few turns.

   • Place the impact cap in front of the locknut and drive the adapter sleeve off the shaft seat with hammer blows.

   • Finally, unbolt the housing
