20213-C3 Single Row Barrel Spherical Roller Bearing 65×120×23mm C3 Clearance Open Type For Crusher Conveyor Machinery GQZ
- 20213-C3 is open single row barrel spherical roller bearing with dimension 65×120×23mm, straight cylindrical inner bore. The outer ring adopts spherical raceway, providing excellent self-aligning function to compensate shaft installation misalignment and slight shaft deflection. Equipped with lightweight polyamide resin cage to separate barrel rollers, stable rotation under medium heavy load. C3 enlarged radial clearance is suitable for equipment with temperature rise and heavy impact working conditions. It can bear large radial loads and moderate bidirectional axial loads simultaneously, widely used for mining crushers, logistics conveyors and heavy general industrial machinery.
