Bearing units can accommodate moderate initial misalignment, but normally do not permit axial displacement.

An insert bearing (Y-bearing) which is based on a single row deep groove ball bearing with a sphered (convex) outside surface and KOYO tr0305a Bearing an extended inner ring a housing, which has a correspondingly sphered but concave bore.

Excellent light load INA Bearings performance Self-aligning ball bearings have low minimum load requirements.

Low noise Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
