71816 CDGB/P4 Bearing Product Overview & Core Advantages
The 71816 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 phenolic cage and universal matching capability (SU) make it ideal for high-speed spindle arrangements and precision machinery where minimal deflection and maximum reliability are critical.

71816 CDGB/P4 Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4 tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0) ensuring exceptional running accuracy and minimal vibration.
Optimized Load Capacity: The 15° contact angle provides excellent performance under combined radial and axial loads, with dynamic load rating of 3285 lbf and static load rating of 4118 lbf.
High-Speed Capability: Features a phenolic resin cage that reduces centrifugal forces and enables limiting speeds up to 28,000 rpm, making it suitable for high-speed spindle applications.
Universal Matching Design: As a universal matchable bearing (SU), it can be paired in sets of three to create preloaded arrangements without selective matching, simplifying installation and maintenance.
Premium Material Selection: Constructed from chrome steel for rings and balls, providing high hardness, wear resistance, and long service life in demanding applications.
