| High Light | 60mm Bore Bearings ，7312B Bearings ，60*130*31 Mm Bearings | ||
The 7312B bearing features a bore diameter of 60 mm, outside diameter of 130 mm, and width of 31 mm. This single row angular contact ball bearing supports both radial and axial loads simultaneously, with axial load accommodation in one direction only. Capable of operating at high speeds, it withstands significantly greater unidirectional axial forces compared to deep groove ball bearings.
