71816 CDGC/P4 Bearing Product Overview & Core Advantages
The 71816 CDGC/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 to handle significant combined loads (radial and axial) simultaneously, while the moderate preload (Class C) ensures minimal deflection and vibration under operational stresses. The open design, combined with phenolic cage and precision lubrication, makes it suitable for high-speed operation up to 28,000 rpm.

71816 CDGC/P4 Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4 tolerance standards with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional accuracy and consistent performance in precision applications.
Optimized Load Capacity: The 15° contact angle design enables efficient handling of 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 friction and enables operation at limiting speeds of 28,000 rpm, making it ideal for high-speed spindle applications.
Thermal Stability: The phenolic cage material and chrome steel construction maintain dimensional stability across the operating temperature range of -30°C to 110°C.
Universal Matching Design: As a Universal Matchable (SU) bearing, it can be precisely matched with other bearings in sets (typically 3 bearings) for optimized preload and performance in complex arrangements.
