    20mm Bore 7304B Single Row Angular Contact Ball Bearing 20*52*15 Mm Open Type

    7304B 20*52*15mm Single Row Angular Contact Ball Bearing


    The 7304B bearing,with a bore diameter of 20 mm, outside diameter of 52 mm, and width of 15 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.
