R4AZZST Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads up to 446 lbf dynamic and 161 lbf static capacity, while accommodating moderate axial loads in both directions.
Shielded Protection: Double metal shields (ZZ) provide effective sealing against contaminants while maintaining low operating torque, making them suitable for high-speed applications up to 36,000 rpm.
Precision Manufacturing: Built to ABEC 1 standards with CN clearance, ensuring consistent performance and smooth operation across the specified temperature range of -30° to 120°C.
Material Excellence: All-chrome steel construction (rings, balls, cage) provides excellent durability, corrosion resistance, and dimensional stability under various operating conditions.
