Insert ball bearings are a kind of multifarious of our standard Ball Bearings which have been modified to fit easily into various types of Mounted Unit Housings and Pillow Blocks. Insert Bearings are supplied with the complete housing however replacement bearings can be purchased separately.

Insert ball bearings are mounted to the shaft by using either an Eccentric or Set Screw type locking collar. This eliminates the requirement of pressing the bearing onto a machined shaft and the need for special installation tools. The self-aligning design helps compensate for alignment errors and the flexing of the shaft.

The insert bearings are the deep groove ball bearings with wide inner rings
Insert ball bearing inserts in housing work as a unit bearing
The housing is mainly casting or pressed steel
The bearing units are compact in design with perfect sealing devices
They can align with ease during operation and can be conveniently mounted or dismounted

The internal structure of the insert ball bearing is the same with that of deep groove ball bearing. But the inner race of this bearing is wider than the outer race. The outer race has the spherical surface. Insert ball bearings can self aligning with the fit between the outer race and the bearing block. Insert ball bearings are compact. It’s easy for loading and unloading. Spherical insert ball bearings often used in mining, metallurgy, textile, transportation machinery, etc.
