6312 Deep Groove Ball Bearing
6312 is a single row deep groove ball bearing with a 60 mm bore, 130 mm outer diameter and 31 mm width, built to the ISO 15 boundary dimensions of the 6300 series. It is size 13 of 19 in the series. It carries radial load and light axial load in both directions at comparatively high speed.
Because the boundary dimensions are fixed by ISO 15, the 6312 is interchangeable with SKF 6312, NSK 6312, FAG 6312 and NTN 6312: it fits the same 60 mm shaft and the same housing bore. Cage material, internal clearance, precision grade and sealing differ between makers and should be confirmed against the application before substitution.
