6307 Ball Bearing
Size 35 x 80 x 21 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6307 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 35 mm bore, a 80 mm outside diameter and is 21 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 6307 is a standard ISO number, the AMB 6307 fits wherever a 6307 from SKF, NBC, FAG, NTN or any other maker is specified.
6307 types we supply
- 6307 open: no shields or seals. Used where the bearing runs in gearbox oil.
- 6307 N: snap ring groove in the outer ring, so a circlip can locate the bearing in the housing.
- 6307 ZZ: metal shields on both sides. Keeps out dust, low friction, good for higher speeds. Also written 6307 2Z or 6307 Z Z.
- 6307 2RS: rubber seals on both sides. Better against water and fine dirt, ideal for wheels and outdoor use. Also written 6307 2RS1, 6307 LLU or 6307 DDU by other makers.
