71824 CDGB/P4 Bearing Product Overview & Core Advantages
The 71824 CDGB/P4 is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Manufactured to P4 tolerance class, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle is optimized for handling combined loads, efficiently supporting significant radial loads alongside axial loads in one direction. The Universal Matchable (SU) design allows for flexible mounting arrangements in pairs to accommodate bidirectional axial loads. With a light preload (Class B), it provides enhanced system rigidity while minimizing friction, making it ideal for high-speed spindle applications and precision machinery where minimal deflection is critical.

71824 CDGB/P4 Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4 tolerance standards with tight dimensional control (bore diameter tolerance: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration in high-speed applications.
High-Speed Capability: Features a phenolic resin cage that reduces centrifugal forces and friction, enabling operation at limiting speeds up to 16,250 rpm. The optimized 35 chrome steel balls with 8.731mm diameter provide balanced load distribution.
Superior Load Capacity: With radial dynamic load rating of 7,470 lbf and static load rating of 10,125 lbf, this bearing delivers reliable performance under significant combined loads. The 15° contact angle efficiently manages both radial and axial load components.
Enhanced Rigidity: The light preload (Class B) configuration increases system stiffness, reducing deflection under operational loads while maintaining optimal thermal characteristics.
Material Excellence: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and durability across the operating temperature range of -30°C to 110°C.
