Heavy duty needle roller bearings NKS series available in 20mm to 135mm bore, consist of a machined and ground channel- shaped outer ring with a complement of needle rollers retained and guided by a cage, and they have lube hole in the outer ring.

The channel-shaped outer ring of high quality chrome steel heat treated can yield maximum load rating. The integral end flanges provide axial location for the needle rollers. The bores of the end flanges serve as piloting surfaces for the cage.

A steel cage can provide inward retention for the needle rollers, and the design assures roller stability and minimizes friction between the cage and the needle rollers. The cage has maximum strength consistent with the inherent high load ratings of needle roller bearings.

Whenever the shaft can be used as the inner raceway, needle roller bearings without inner rings NKS series provides advantages of economy and close control of radial internal clearance in operation.

Application

The needle roller bearings are commonly used in automotive transmissions, intermediate steering shafts, two-cycle engines, construction equipment, planetary gear reducer, wheel drum, agricultural machinery etc.
