    55mm Bore 7311B Single Row Angular Contact Ball Bearings 55*120*29 Mm Open Type

    7311B 55*120*29mm Single Row Angular Contact Ball Bearing


    The 7311B bearing,with a bore diameter of 55 mm, outside diameter 120 mm, and width of 29 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.
