71914 ACD/P4ATGB Bearing Product Overview & Core Advantages
The 71914 ACD/P4ATGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in sets of three, it enables optimized preload configurations for superior system performance. Its 25° contact angle provides excellent capacity for combined radial and axial loads, while the P4A tolerance class ensures minimal runout and vibration. This bearing is pre-lubricated and operates effectively across a wide temperature range from -30°C to 110°C, making it ideal for high-speed, high-precision applications.

71914 ACD/P4ATGB Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 25° contact angle and precision-ground raceways provide exceptional load distribution, enabling the bearing to handle significant radial and axial loads simultaneously.
High-Speed Capability: The phenolic cage offers excellent strength-to-weight ratio and smooth operation at the limiting speed of 28,000 rpm, reducing centrifugal forces and maintaining stability.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for precision applications.
Universal Matching Design: As part of a universal matchable set of three bearings, this configuration allows for flexible mounting arrangements and optimized preload (Light / Class B) for enhanced system rigidity.
