FRW2zz Bearing Structural Features & Performance Benefits
Compact Flange Design: The integrated flange (0.44" OD) provides secure mounting and axial location without additional components, reducing assembly complexity and space requirements.
Radial Load Capacity: With a dynamic load rating of 121 lbf and static load rating of 39 lbf, this bearing handles significant radial loads in compact spaces, supported by 7 precision chrome steel balls.
High-Speed Capability: The stainless steel cage and optimized ball complement enable smooth operation at limiting speeds up to 110,000 rpm, making it suitable for high-speed applications.
Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group) ensures consistent running accuracy and minimal vibration.
Extended Service Life: Double stainless steel shields protect the bearing interior while the chrome steel construction provides excellent wear resistance across the specified temperature range.
