71914 CEGA/HCP4A Bearing Product Overview & Core Advantages
The 71914 CEGA/HCP4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and speed capability. Manufactured to P4A super-precision tolerance, this bearing delivers superior running accuracy and dimensional stability. Its 15° contact angle provides optimal performance for combined radial and axial loads, while the ceramic balls and phenolic cage enable high-speed operation up to 28,000 rpm. This bearing comes pre-lubricated and is universally matchable, allowing for flexible mounting configurations in precision assemblies.

71914 CEGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The combination of chrome steel rings and ceramic balls provides superior high-speed performance, reduced friction, and extended service life. Ceramic balls offer excellent dimensional stability and reduced centrifugal forces at high rotational speeds.
Phenolic Cage Construction: The phenolic resin cage ensures smooth operation at high speeds with excellent strength-to-weight ratio and minimal friction characteristics, contributing to the bearing's 28,000 rpm limiting speed.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore tolerance: -0.004mm to 0, OD tolerance: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration for precision applications.
Universal Matchability: Designed as universally matchable (SU), these bearings can be arranged in various configurations (back-to-back, face-to-face, or tandem) to meet specific application requirements for rigidity and load capacity.
