71914 ACE/P4ATGA Bearing Product Overview & Core Advantages
The 71914 ACE/P4ATGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This P4A tolerance class bearing features an extra light preload (Class A) and is universally matchable (SU), allowing for flexible mounting configurations in preloaded sets. Its optimized 25° contact angle enables it to handle combined loads efficiently, supporting high radial loads alongside significant axial loads in one direction. The phenolic cage and superior manufacturing standards make it ideal for high-speed operation up to 31,000 rpm, providing high rigidity and stable performance in demanding environments.

71914 ACE/P4ATGA Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional dimensional stability and running accuracy for high-precision applications.
Optimized Internal Geometry: The 25° contact angle and carefully calculated raceway geometry provide optimal load distribution, enabling superior performance under combined radial and axial loads.
High-Speed Capability: The phenolic cage offers excellent strength-to-weight ratio and operates effectively at high speeds, contributing to the bearing's limiting speed of 31,000 rpm while maintaining dimensional stability.
Universal Matching Design: As a universally matchable (SU) bearing, it can be mounted in various preloaded arrangements (DB, DF, DT) without selective matching, simplifying installation and maintenance procedures.
Superior Load Capacity: With a dynamic load rating of 10,102 lbf and static load rating of 10,238 lbf, this bearing delivers reliable performance under demanding operating conditions.
