Semi-circular needle roller bearings are usually an indispensable part of the automotive industry. They are different from needle roller bearings not only in shape, but also in performance and function. So what changes have taken place after semi-circular needle roller bearings have been installed on the corresponding devices?
When semi-circular needle roller bearings are installed in the brakes of automobiles, their concave and convex axles will not be worn out by frequent swings. That is to say, because of the toughness of the outer raceway of the semi-circular needle roller bearing, it can effectively resolve various strong impact forces. When the bearing pressure moves, the concave-convex axle does not contact directly, so it will not produce noise, nor will it produce high temperature. It effectively guarantees the safety of driving and prolongs the service life of the brake.
Compared with ordinary bearings, semi-circular needle roller bearings have obvious advantages. For example, they can maintain the bearing function under large load, while ordinary bearings can not do so, and their rotation will be hindered after being under heavy pressure. Because the cylindrical bodies with small diameter and dense arrangement in semi-circular needle roller bearings are in line contact, the contact force surface is large, the diameter of the roller is small and the rotation is flexible, and the average spreading pressure is greatly reduced under heavy pressure, so the rotation function of the roller bearings can not be affected at all.
Secondly, in the design of semi-circular needle roller bearings, thin-walled high-quality steel plate is used as the outer raceway material, while the inner raceway uses the original camshaft, so its rolling body diameter is small, which can save more installation space. Not only is the material special, but also the manufacturing technology of semi-circular needle roller bearing is special. Its shell is extruded by high quality cold plate, and its surface is also treated by carbonitriding.
In this way, the semi-circular needle roller bearings not only have strong hardness and wear resistance, but also have good toughness. They will not break and break when subjected to strong impact, and further extend their service life.
