SFR0zz Bearing Structural Features & Performance Benefits
Compact Flanged Design: The integrated flange (0.203" OD) enables secure and precise mounting, simplifying assembly and improving positional accuracy in compact assemblies.
Stainless Steel Construction: All components—rings, balls, and cage—are manufactured from stainless steel, providing superior corrosion resistance and making it suitable for harsh environments and cleanroom applications.
High-Speed Capability: With a limiting speed of 99,000 rpm and a stainless steel cage, this bearing is optimized for high-velocity operation, reducing friction and heat generation.
Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), ensuring smooth and consistent operation with minimal vibration.
Shielded Protection: The non-contact stainless steel shields help retain lubricant and exclude contaminants, extending service life without significantly impacting speed performance.
