FR2zz Bearing Structural Features & Performance Benefits
Flanged Design: The integrated flange (0.44" outer diameter) provides precise axial location and simplifies mounting in housing structures, enhancing installation accuracy and reducing assembly time.
Optimized Load Capacity: With a radial dynamic load rating of 121 lbf and static load rating of 39 lbf, this bearing delivers reliable performance under substantial radial loads while maintaining smooth operation.
High-Speed Capability: The stainless steel cage and seven precision chrome steel balls (0.06252" diameter) enable stable operation up to 56,000 rpm, making it suitable for high-speed applications.
Enhanced Protection: Double stainless steel shields effectively retain lubricant and exclude contaminants, extending bearing service life and reducing maintenance requirements.
Precision Engineering: Manufactured to ABEC1 tolerance standards with MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance and minimal vibration.
