This machined type caged needle roller bearing NA series combines a collared outer ring with special lightweight rigid cage and needle rollers. During operation, needle rollers are guided precisely by the cage, and an ideal load distribution is obtained.

Needle roller bearings NA series with ribs are ready-to-fit units. For NA series, the outer ring and needle roller and cage assembly form a self-retaining unit. The needle roller and cage assembly is guided by the ribs on the outer ring. The bearings are available with or without an inner ring, in a single or double row design, open or sealed versions. Bearings without an inner ring are highly suitable for bearing arrangements with particularly compact radial dimensions, if the shaft raceway can be hardened and ground. Bearings with an inner ring are used if the shaft cannot be configured as a rolling bearing raceway.

Therefore, the physical ferrule needle roller bearing can meet the requirements of light weight, small space occupation and large transmission power. Solid ferrule needle bearings have a small volume and high load carrying capacity.

Application

The needle roller bearings are suitable for many applications, such as automatic transmissions, manual transmissions, automotive accessories, power tools, mechanical pumps, industrial machinery etc.
