Heavy Duty Needle Roller Bearings
Overview: Heavy duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers, and a cage. The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitates re-lubrication. These bearings can be used with or without a machined and ground inner ring, depending on the suitability of the shaft as a raceway surface.

● Applications: Gear pumps, sheaves, automotive transmissions and two-cycle engines.
● Features: Thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section.
● Types:
Metric sizes: NK, NKI, NKIS, NA48, NA49, NA69, RNA48, RNA49, RNA69, RNA49..RS, RNA49..2RS
Inch sizes: NCS, BR, HJ, HJ..RS, HJ..2RS
