6308 Ball Bearing
Size 40 x 90 x 23 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6308 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 40 mm bore, a 90 mm outside diameter and is 23 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 common in gearboxes, alternators, pumps, three-wheeler and car transmissions, and farm equipment. Because 6308 is a standard ISO number, the AMB 6308 fits wherever a 6308 from SKF, NBC, FAG, NTN or any other maker is specified.
6308 types we supply
- 6308 open: no shields or seals. Used where the bearing runs in gearbox oil.
- 6308 N: snap ring groove in the outer ring, so a circlip can locate the bearing in the housing.
- 6308 ZZ: metal shields on both sides. Keeps out dust, low friction, good for higher speeds. Also written 6308 2Z or 6308 Z Z.
- 6308 2RS: rubber seals on both sides. Better against water and fine dirt, ideal for wheels and outdoor use. Also written 6308 2RS1, 6308 LLU or 6308 DDU by other makers.
