71914 ACDGC/P4A Bearing Product Overview & Core Advantages
The 71914 ACDGC/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Operating under the stringent P4A tolerance class, this bearing is designed to handle significant combined loads, particularly thrust loads in one direction, while maintaining high-speed capabilities up to 29,000 rpm. Its universal matchable (SU) design allows for flexible mounting in duplex pairs (back-to-back or face-to-face) to accommodate complex load scenarios, making it an ideal component for high-rigidity and precision spindle systems.

71914 ACDGC/P4A Bearing Structural Features & Performance Benefits
High-Precision Construction: Manufactured to P4A tolerance standards with extremely tight dimensional tolerances (bore and OD: -0.004mm to 0), ensuring minimal runout and vibration for superior rotational accuracy.
Optimized Contact Angle: The 25° contact angle provides an excellent balance between radial and axial load capacity, making it particularly effective for applications with significant thrust loads.
Advanced Cage Design: The phenolic resin cage offers superior performance at high speeds, providing reduced friction, excellent dimensional stability, and compatibility with various lubrication methods.
High-Speed Capability: Engineered internal geometry and cage design enable operation at limiting speeds of 29,000 rpm, suitable for demanding spindle applications.
Universal Matching: As a Universal Matchable (SU) bearing, it can be precisely paired with another identical bearing to create preloaded sets, enhancing system rigidity and load distribution.
