6309 Ball Bearing
Size 45 x 100 x 25 mm. Single row deep groove ball bearing by AMB Bearings, Ahmedabad.
The 6309 is a single row deep groove ball bearing from the 6300 series (medium series, for heavier loads). It has a 45 mm bore, a 100 mm outside diameter and is 25 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 6309 is a standard ISO number, the AMB 6309 fits wherever a 6309 from SKF, NBC, FAG, NTN or any other maker is specified.
6309 types we supply
- 6309 open: no shields or seals. Used where the bearing runs in gearbox oil.
- 6309 N: snap ring groove in the outer ring, so a circlip can locate the bearing in the housing.
- 6309 ZZ: metal shields on both sides. Keeps out dust, low friction, good for higher speeds. Also written 6309 2Z or 6309 Z Z.
- 6309 2RS: rubber seals on both sides. Better against water and fine dirt, ideal for wheels and outdoor use. Also written 6309 2RS1, 6309 LLU or 6309 DDU by other makers.
