627/W64 Bearing Structural Features & Performance Benefits
Solid Oil Lubrication Technology: The integrated solid oil matrix provides continuous lubrication throughout the bearing's service life, eliminating the need for re-lubrication and preventing lubricant leakage in sensitive applications.
Optimized Radial Load Capacity: With a dynamic load rating of 629 lbf and static load rating of 248 lbf, this bearing delivers reliable performance under substantial radial stresses while maintaining dimensional stability.
High-Speed Capability: The limiting speed of 30,000 rpm is achieved through precision manufacturing and the advanced solid oil system that reduces friction and heat generation at high rotational velocities.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance standards with CN radial internal clearance, ensuring consistent performance and smooth operation in precision applications.
