71914 CDGA/P4A Bearing Product Overview & Core Advantages
The 71914 CDGA/P4A is a single-row angular contact ball bearing designed for ultra-precision applications requiring exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior dimensional stability and minimal runout. Its 15° contact angle and extra light preload (Class A) configuration make it ideal for handling combined radial and axial loads while maintaining smooth operation at limiting speeds up to 24,000 rpm. The phenolic cage and universal matching capability further enhance its suitability for high-precision spindle arrangements.
