    45mm Bore 7309B Single Row Angular Contact Ball Bearings 45*100*25 Mm Open Type

    7309B 45*100*25mm Single Row Angular Contact Ball Bearing


    The 7309B bearing,with a bore diameter of 45 mm, outside diameter 100 mm, and width of 25 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.
