RW168zz Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial loads with a dynamic load rating of 71 lbf. The precisely matched chrome steel balls (11 pieces, 0.0394" diameter) ensure smooth operation and extended service life.
Enhanced Contamination Resistance: Double stainless steel shields (300 series) provide superior protection against dust and particulate ingress, maintaining bearing integrity in challenging environments while requiring minimal maintenance.
Precision Engineering: Manufactured to ABEC1 tolerance standards with controlled radial internal clearance (MC3: 0.00008" to 0.0005"), ensuring consistent performance and reliable positioning accuracy in precision assemblies.
Extended Inner Ring Design: The 0.1562" wide inner ring provides additional mounting surface and facilitates secure axial location, enhancing installation stability and simplifying assembly processes.
