Needle roller bearings are a roller bearing, although sometimes the roller size slightly beyond the definition of the needle size range, but usually still known as needle roller bearings.

Needle roller bearings, according to bear the direction of the load can be divided into radial bearings and thrust bearings. Among them, the radial bearings include: a variety of series of stamping outer ring type, solid type, as well as special-purpose bolt type and track roller needle roller bearings.

 Needle roller and cage assemblies

NSK needle roller and cage assembly easy to use, the use of joint needle roller will not fall off. Occupied by the design space is small, but has a great carrying capacity. As the cage structure is unique, can accurately guide the needle, lubrication ideal, it can be used at high speed. Needle roller with a convex degree, can ease the small installation error and deformation of the shaft caused by the end of the needle stress concentration, extended bearing life.

Drawn cup needle roller bearings

NSK Drawn Cup Needle Roller Bearings (with cage type and full complement roller type) has a unique outer ring structure, is a rolling bearing with many specialties of a class of bearings, these features include: the outer wall thickness of the thinnest, load capacity Large; the use of specially selected special alloy steel plate, with a high limit load; cage through the surface hardening treatment, abrasion resistance; high speed limit, easy installation and so on.

Solid needle roller bearings

Solid needle roller bearings with high precision, small footprint design space, carrying capacity. Its application is very extensive.

Ferrule with a rigorous selection of vacuum degassing bearing steel or carburizing steel, heat treatment, the fine grinding process. With a strong double-walled outer ring, with a number of high degree of convex with a certain degree of precision needle.

Cage light weight, toughness strong, accurate and smooth guide large diameter needle

Thrust bearings

Thrust needle roller bearings, with metric and imperial.

Thrust needle roller and cage in the cage, by the two semi-cage interlocking, with precision steel plate stamping and surface hardening treatment. High-precision needle roller assembly to the cage, so that it has high strength and wear resistance. While the needle is fully maintained by the cage, can withstand a larger axial load, while rotating smoothly. Moreover, the assembly space is small, easy to the original thrust washers (ring ring, seat ring, the same below) replacement. The needle roller and cage assembly, with a number of different thickness of the thrust washer, it can be based on the bearing around the assembly conditions, select the best thickness of the thrust washer.

Bolt type roller needle roller bearings

Bolt type roller needle roller bearings, outer ring wall thickness, needle roller with a crown, double-headed bolt raceway surface after hardening treatment, with a certain toughness, can withstand the impact load.
