Structural Features and Performance Benefits
Single Row Deep Groove Design: The optimized raceway geometry provides excellent radial load capacity (805 lbf dynamic rating) while accommodating moderate axial loads in both directions.
Full Stainless Steel Construction: All components including rings, balls, and cage are manufactured from stainless steel, ensuring corrosion resistance and compatibility with various operating environments.
Integrated Shield Protection: The 2Z shields effectively retain lubricant and exclude contaminants, contributing to extended service life and reliable performance.
Precision Manufacturing: With P0 tolerance class and controlled radial internal clearance (CN), this bearing delivers consistent precision performance and smooth operation up to 17,000 rpm.
Pre-lubricated Design: Factory-applied grease lubrication ensures immediate operation and maintenance-free service within the specified temperature range (-30° to 120°C).
