71814 ACD/HCP4 Bearing Structural Features & Performance Benefits
High-Speed Capability: The combination of ceramic balls and phenolic resin cage enables exceptional performance at limiting speeds up to 24,000 rpm. Ceramic balls reduce centrifugal forces and provide better thermal stability.
Precision Performance: Manufactured to P4 tolerance class with tight dimensional control (bore tolerance: -0.007mm to 0), ensuring minimal runout and vibration for precision applications.
Optimized Load Capacity: The 25° contact angle provides excellent combination load handling with radial dynamic load rating of 2925 lbf and static load rating of 3375 lbf.
Thermal Stability: Phenolic cage material offers excellent dimensional stability across the operating temperature range of -30° to 110°C.
Preload Advantage: Factory preloading eliminates the need for adjustment during installation and ensures immediate high rigidity and precise rotational characteristics.
