Heavy-duty Needle roller bearings consist of a machined and ground channel-shaped outer ring with a component of needle rollers retained and guided by a cage. The high-strength cage retains and guides the rollers. An optional groove and hole in the outer ring facilitate relubrication. These bearings can be used with or without a machined or ground inner ring, depending on the suitability of the shaft as a raceway surface.
APPLICATIONS: Gear pumps, sheaves, automotives transmissions and two-cycle engines.
TYPES: With flanges - NK / NKI / NKS / NKIS / NA48 / RNA48 / NA49 / RNA49 / NA69 / RNA69, without flanges - NAO / RNAO
