Semicircular needle roller bearings are usually an indispensable bearing part in the automotive industry. They are not only different from needle roller bearings in shape, but also in performance and function. So after installing the semicircular needle roller bearings on the corresponding device, what changes have occurred?

When a semicircular needle roller bearing is installed in the brake of an automobile, its concave-convex shaft movement surface will not be worn out due to frequent swings. In other words, because the semicircular needle roller bearing has a tough outer raceway, it can effectively resolve various strong impact forces. The concave and convex shafts do not directly contact when the pressure is applied, so that no noise or high temperature is generated. , Which effectively guarantees driving safety and prolongs the service life of the brake.

Compared with ordinary bearings, the advantages of semicircular needle roller bearings are also very obvious. For example, it can maintain the bearing function under a large load, which is not possible with ordinary bearings. It rotates even after being stressed. Will be blocked. Since the small diameter and densely arranged roller bodies in the semicircular needle roller bearing are in line contact, the contact bearing surface is large, and the rolling element diameter is small and the rotation is very flexible. The even pressure is greatly reduced when subjected to heavy pressure, so it has no effect Its rotation function.

Secondly, because the semicircular needle roller bearing is designed with thin-walled high-quality steel plate as the outer raceway material, and the inner raceway uses the original convex shaft, its rolling element diameter is small, which can save more installation space. Not only the material is special, but the manufacturing process of the semicircular needle roller bearing is also very special. Its shell is made of high-quality cold plate extrusion, and the surface is also treated by carbonitriding.

In this way, the semicircular needle roller bearing not only has strong hardness to resist abrasion, but also has good toughness. It will not break and break when subjected to strong impact, further extending its service life.
