BA1B 311576 Bearing Structural Features & Performance Benefits
High Load Capacity Design: The 40° contact angle and optimized raceway geometry enable superior axial load carrying capacity while maintaining excellent radial load performance. With a radial dynamic load rating of 101,025 lbf and static load rating of 285,750 lbf, this bearing delivers exceptional durability under demanding conditions.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore tolerance: -0.05mm to 0, outside diameter tolerance: -0.06mm to 0), ensuring precise fitment and minimal runout for high-precision applications.
Advanced Material Construction: Utilizing chrome steel for both rings and balls, combined with a nylon cage, provides excellent strength-to-weight ratio and smooth operation. The cage design contributes to stable performance at the limiting speed of 0.6 × 1000 rpm.
Thermal Stability: Operating temperature range of -30° to 110°C ensures reliable performance across diverse environmental conditions while maintaining dimensional stability.
