NSK needle roller and cage assembly
The NSK needle roller and cage assembly are easy to install and use, and the integrated needle roller does not fall off. The occupied design space is small, but it has a large carrying capacity. Thanks to the unique structure of the cage, the needle can be precisely guided and lubricated, so it can be used at high speed. The needle roller busbar has a convexity, which can alleviate the stress concentration at the end of the needle roller caused by the slight installation error and the deformation of the shaft, and prolong the service life of the bearing.
Drawn outer ring NSK needle roller bearing
NSK needle roller bearing (with cage type and full complement needle roller type) has a unique outer ring structure and is a kind of bearing with many special features in rolling bearings. These features include: outer ring wall thickness is the thinnest, load capacity Large; Made of specially selected special alloy steel plate with high ultimate load; the frame is hardened by surface hardening, high resistance to wear; high speed limit and easy installation.
Solid NSK needle roller bearing
The solid NSK needle roller bearing has high precision, occupying a small design space and strong carrying capacity. Its application is very extensive.
The ferrule is made of carefully selected vacuum degassing bearing steel or carburized steel, and is subjected to fine grinding after heat treatment. The outer ring with a solid double rib is equipped with a number of high-precision needles with a certain degree of convexity.
The cage is light in weight and extremely tough, and can guide large diameter needles accurately and smoothly.
Thrust NSK needle roller bearing
Thrust NSK needle roller bearing, available in metric and imperial styles.
The cage of the thrust NSK needle roller bearing and the cage assembly is interlocked by two semi-cage brackets, precision stamped by steel plates and surface hardened. High-precision needle rollers are assembled into the cage for high strength and wear resistance. The needle is fully retained by the cage and can withstand large axial loads while rotating smoothly. Moreover, the assembly space is small, and it is easy to replace the original thrust washer (the general term of the shaft ring and the seat ring, the same below). The needle roller and cage assembly is equipped with several thrust washers of various thicknesses, so the optimum thickness of the thrust washer can be selected according to the assembly conditions around the NSK needle roller bearing.
Bolt type roller NSK needle roller bearing
NSK needle roller bearing, the outer ring wall thickness, the needle roller busbar with convexity, the raceway surface of the stud bolt is hardened, has certain toughness, and can withstand impact loads.
Retaining ring type roller NSK needle roller bearing
NSK needle roller bearing, outer ring wall thickness, needle roller busbar with convexity, high load capacity, can withstand impact loads. This type of bearing is non-separable and easy to use. It is widely used in rollers, cams, rocker arms, etc.
