QIBR XV Series Crossed Cylindrical Roller Bearings: Material Options and Application Selection Guide
The QIBR XV Series Crossed Cylindrical Roller Bearings feature an integrated inner ring design, making them ideal for applications requiring high rotational precision of the inner ring. These bearings are equipped with seals to prevent contaminants from entering the bearing and to reduce grease leakage, lowering maintenance costs. Both axial and radial sides have lubrication holes for multi-directional oil injection. The outer ring is designed with mounting holes, making the bearings easy to connect.
The QIBR XV Series Crossed Cylindrical Roller Bearings are typically made from AISI 52100 material, known for its excellent wear resistance and strength, making it suitable for high-load applications.
Additionally, the bearings can be made from AISI 440C stainless steel for applications in harsh environments.
The choice of material depends on specific application requirements, including load, strength, and environmental conditions, ensuring optimal performance and service life of the bearings. By considering these factors, users can effectively select the right bearings for their needs.
