7014 CEGA/HCP4AL1 Bearing Product Overview & Core Advantages
The 7014 CEGA/HCP4AL1 is a single-row angular contact ball bearing engineered for ultra-high precision applications. Its defining characteristics include P4A super-precision tolerance, a 15° contact angle, and a phenolic resin cage. This bearing is universally matchable (SU designation), allowing for precise preload control when mounted in sets. The combination of a ceramic ball material and extra light preload (Class A) enables exceptional high-speed performance up to 27,000 rpm, while maintaining superior running accuracy and rigidity.

7014 CEGA/HCP4AL1 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and silicon nitride (Si3N4) ceramic balls significantly reduces centrifugal forces, enabling higher limiting speeds while providing electrical insulation properties.
Phenolic Resin Cage: The phenolic cage material offers excellent strength-to-weight ratio and operates effectively at high speeds with minimal friction, contributing to the bearing's 27,000 rpm limiting speed.
Precision Engineering: With P4A tolerance class and bore/OD tolerances of -0.004mm to 0, this bearing ensures exceptional running accuracy and minimal vibration for demanding applications.
Optimized Load Capacity: The 15° contact angle provides balanced performance for combined radial and axial loads, with dynamic and static load ratings of 5355 lbf and 4118 lbf respectively.
