R0zz Bearing Structural Features & Performance Benefits
Precision Engineering: The bearing's single row design with 7 precision balls (0.0236" diameter) provides optimal load distribution and smooth rotation characteristics. The stainless steel cage ensures proper ball guidance and stability at the limiting speed of 110,000 rpm.
Enhanced Durability: Constructed from chrome steel rings and stainless steel components, this bearing offers superior wear resistance and mechanical strength. The combination provides excellent performance across a wide temperature range from -86 to 230 °F.
Radial Load Capacity: With a dynamic load rating of 21 lbf and static load rating of 6 lbf, this compact bearing delivers reliable performance in space-constrained applications while maintaining dimensional stability under load.
Contamination Protection: The 300 series stainless steel shields effectively exclude contaminants while minimizing friction, making this bearing suitable for applications where lubrication retention and contamination exclusion are critical.
