Features of Silicon Carbide Bearing
Silicon carbide bearings are mainly made of high-purity silicon carbide (SiC) powder. Here are the main features of NKM silicon carbide bearings.
Advanced manufacturing technology ensures highly accurate dimensions, improving stability of operation.
Under certain conditions, an oxide film will form on the surface of the bearing, which can reduce friction and wear.
Withstand high temperatures up to 1650℃ without deformation. Ideal for various industrial machinery.
Bending strength of 400-490 MPa, better compression and impact resistance.
A lower friction coefficient can reduce equipment loss and reduce the operating cost of the equipment.
Resistant to strong acids (except hydrofluoric acid) and strong alkalis, stable performance, and not easily corroded.
The thermal conductivity is 100-120 W/m.k, which can quickly dissipate the heat generated during operation.
Silicon carbide bearings can maintain good stability with rapid changes in temperature.

Different industries and applications require different ball bearings. The optimum ball bearings are those that are able to fully meet the requirements of the industry’s application conditions. Below are some of the most popular ball bearing types and characteristics:
① Deep groove ball bearings, the most universally used type and are capable of supporting radial loads and certain axial loads at the same time.
② Angular contact ball bearings, which are mainly used in machine tool spindles, industrial robot joints, aircraft engine high-speed rotors, etc.
③ Thrust ball bearings, which are mainly used in resisting axial loads and have a simple structure.
There are different types of bearings, and ball bearings are one of them. Bearings have good shock resistance, impact resistance, low frictional coefficient and low starting resistance. Apart from the above properties, ball bearings have a greater limit speed and are suitable for high-speed rotating positions.
Under identical operating conditions, including the same speed, capacity to carry a load, operating temperature, mode of installation and component materials, rolling bearings and sliding bearings survive longer.
In general, ceramic ball bearings are better than steel ball bearings because:
① The two differ in hardness. Generally speaking, Rockwell hardness of ceramic balls can be up to HRA80-90, but for the hardness of the bearing steel ball it is primarily HRC60-65, hence the ceramic ball bearings have more wear resistance and life.
② Multiple high temperature resistance. The maximum temperature resistance of ceramic ball bearings can reach as high as 1650℃, which is much higher than that of steel ball bearings. Therefore, ceramic materials are more appropriate in high temperature environments.
③ Multiple weights. The density of steel is greater than that of ceramics, and therefore steel ball bearings are heavy, which will affect the equipment’s life.
④ Different corrosion resistance. Ceramic material has very good chemical stability and is hard to react with chemical materials, while steel ball bearings are prone to rust in the majority of environments.
