71914 ACD/P4ADGC Bearing Product Overview & Core Advantages
The 71914 ACD/P4ADGC is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This universal matchable (SU) bearing features a 25° contact angle and moderate preload (Class C), enabling it to handle combined radial and axial loads simultaneously. Manufactured to P4A tolerance class, it delivers superior running accuracy and is particularly suitable for high-speed operation up to 28,000 rpm. The phenolic cage and chrome steel construction ensure reliable performance across a temperature range of -30°C to 110°C.

71914 ACD/P4ADGC Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 25° contact angle and carefully calculated ball diameter (9.525mm) with 24 balls provide an optimal balance between load capacity and high-speed capability.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional tolerances (bore/OD: -0.004mm to 0), ensuring minimal runout and vibration for precision applications.
High-Speed Performance: The phenolic cage offers excellent strength-to-weight ratio, contributing to the bearing's ability to reach 28,000 rpm limiting speed while maintaining stability.
Universal Matching Capability: As Universal Matchable (SU) bearings, they can be arranged in various configurations (back-to-back, face-to-face, or tandem) without additional spacers, simplifying installation and maintenance.
Robust Load Capacity: With dynamic load rating of 11,858 lbf and static load rating of 14,400 lbf, this bearing delivers reliable performance under significant combined loads.
