The inner and outer rings are made of standard long-life bearing steel, which reduces the content of non-metallic inclusions


Rollers are usually made of steel balls or ceramic balls,


The steel ball is also made of long-life, high-performance materials, with stronger resistance to adhesion, wear resistance and rolling fatigue life.


Ceramic rolling element bearing has realized the requirements of super high speed and super high precision rotation that metal rolling element bearing cannot reach, and won the praise of the majority of users.


Holder


Ball guided polyamide resin cage, friction resistance, low noise, short running in time with grease, stable temperature rise.


The outer ring guide phenolic resin cage adopts the outer ring guide, which has excellent high-speed performance and stable temperature rise performance.


PEEK resin holder. It can realize high speed operation performance of 3.3 million dmn and high performance cage with low temperature rise.
