The needle and cage assembly is an independent bearing element, each of which is guided and maintained precisely. Needle roller surface modification is adopted not only in the process of using design to eliminate the edge stress, and the processing method of the special end surface smooth transition, the maximum extent, to improve the operation performance and service life.
The needle and cage assembly is a fast assembly of independent parts. They are an excellent choice for highly rigid and high-bearing bearing configurations. If the shaft and bearing holes can be used as raceway, the needle and cage assembly requires only a small radial space.
A large number of rollers and maintenance components are only partially listed in the product table. We also provide other dimensions and maintenance components that are different from the standard design, such as the splicing needle cage, which can be used in the application of the raceway.
