Radial insert ball bearings with adapter sleeve - INA GSH

In the case of this series, the inner ring is located on the shaft by means of an adapter sleeve with a locknut and a tab washer 
These radial insert ball bearings are suitable for shafts up to tolerance class h11 ?.

The bearings can be relubricated.

This location method is suitable for bearing arrangements with a constant or alternating direction of rotation and for high speeds.

The adapter sleeve and locknut give concentric, force locking location of the bearing inner ring on the shaft. As a result, the speeds that can be achieved are approximately the same as with deep groove ball bearings. These bearings also give quieter running than normal radial insert ball bearings. The adapter sleeve, locknut and tab washer are all zinc-coated.

The bearings are highly suitable for reversing operation. As a result of the force locking connection, there is no occurrence of fretting corrosion between the shaft and the bore of the adapter sleeve. 

Due to the integral adapter sleeve, the bearings have the same radial dimensions as, and slightly lower basic load ratings than, radial insert ball bearings with an eccentric locking collar, or with grub screws in the inner ring, and are interchangeable with these bearings.
