QIBR SX Series Crossed Cylindrical Roller Bearings: Material Options and Application Selection Guide
The QIBR SX Series Crossed Cylindrical Roller Bearings, with an integrated inner ring structure, are most suitable for applications requiring high rotational accuracy of the inner ring. The outer ring is split into two parts and fixed together by three retaining rings.
The QIBR SX Series Crossed Cylindrical Roller Bearings typically use AISI 52100 steel, which offers excellent wear resistance and strength, ideal for high-load environments.
For applications in harsh conditions, the SX Series can be made from AISI 440C stainless steel. The material selection depends on specific application needs, such as load, strength, and environmental conditions, to ensure optimal performance and service life.
