Spherical roller bearing outer ring and bearing housing bore should not be an interference fit with the inner ring and the journal also should not be too tight, used in the installation nut adjustment should be able to produce a more flexibleaxial displacement. Spherical roller bearings with interference fit, easy to make the change in the contact angle of the bearing, resulting in uneven distribution of bearing loads caused by the high temperature rise. Therefore, these bearings inner and outer rings with the journal and the bearing housing hole installation with general hands thumb bearings can just push into the journal and the housing bore for the best.

1. It consists of one piece of machined brass cage, one inner ring with double flanges and one guide ring centred on the inner ring. The limit speed is higher , and have a relatively small noise .

2. One annular groove and three lubrication holes on the outer ring.
