7308B 40*90*23mm Single Row Angular Contact Ball Bearing
The 7308B bearing,with a bore diameter of 40 mm, outside diameter 90 mm, and width of 23 mm.This single row angular contact ball bearing can support both radial and axial loads simultaneously, with the axial load being accommodated in one direction only. Depending on the specific model, this bearing is capable of operating at high speeds or even extremely high speeds. Compared to deep groove ball bearings, it can withstand significantly greater unidirectional axial forces.It is particularly well-suited for situations needing robust handling of both radial and significant unidirectional axial loads at high speeds.
