| MB | Brass cage (machined) for optimal high-speed performance |
71976 ACGAMB Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The 25° contact angle and precision-ground raceways enable superior performance under combined radial and axial loads. With a dynamic load rating of 92,250 lbf and static load rating of 165,375 lbf, this bearing delivers reliable operation in demanding conditions.
High-Speed Capability: The machined brass cage (MB) ensures dimensional stability and reduced friction at high rotational speeds, supporting a limiting speed of 1,300 rpm. The optimized internal geometry minimizes heat generation during operation.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore tolerance: -0.03mm to 0, OD tolerance: -0.038mm to 0), this bearing guarantees precise shaft positioning and minimal runout.
Durable Construction: Components made from chrome steel provide excellent wear resistance and fatigue strength. The open design allows for customized lubrication schemes to match specific application requirements.
