Size 60 x 130 x 31 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6312 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 60 mm bore, a 130 mm outside diameter and is 31 mm wide. It carries radial load with some axial load in both directions and runs smoothly at high speed.
Sizes in this bore range are used in tractor and truck gearboxes, heavy pumps, industrial gear units and machinery. Because 6312 is a standard ISO number, the AMB 6312 fits wherever a 6312 from SKF, NBC, FAG, NTN or any other maker is specified.
