71916 CD/P4ADGC Bearing Product Overview & Core Advantages
The 71916 CD/P4ADGC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This universal matchable bearing features a 15° contact angle and moderate preload (Class C), making it ideal for arrangements that must handle combined loads—significant radial and axial loads simultaneously. Manufactured to P4A tolerance class, it delivers superior running accuracy and high-speed capability, with a limiting speed of 28,000 rpm. Its phenolic cage and optimized internal geometry contribute to smooth operation and high rigidity in precision machinery.

71916 CD/P4ADGC Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 15° contact angle provides an ideal balance between radial and axial load capacity, enabling efficient handling of combined loads in both directions.
High-Speed Phenolic Cage: The phenolic resin cage ensures excellent dimensional stability at high speeds, contributing to the bearing's 28,000 rpm limiting speed while reducing friction and heat generation.
Precision Manufacturing: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for high-precision applications.
Universal Matching Capability: Designed as Universal Matchable (SU) bearings, they can be mounted in various preloaded arrangements without selective matching, simplifying installation and maintenance.
Robust Load Capacity: With dynamic load rating of 13,320 lbf and static load rating of 17,550 lbf, this bearing delivers reliable performance under demanding operating conditions.
