71914 FEGA/HCP4A Bearing Product Overview & Core Advantages
The 71914 FEGA/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. As a single bearing in a universally matchable (SU) set, it enables precise preload control when paired. Its ceramic ball construction and P4A super-precision tolerance deliver superior running accuracy, reduced heat generation, and extended service life in high-speed applications up to 28,000 rpm. The combination of an 18° contact angle and extra light preload (Class A) provides optimal stiffness for managing combined radial and axial loads.

| Code Segment | Technical Meaning |
|---|---|
| 71914 | Basic bearing designation indicating size series and bore diameter |
| FE | Steel cage with glass fiber reinforced polyamide 66 (providing excellent high-speed capability and reduced friction) |
| GA | Universal matchable bearing with specific preload and tolerance pairing capability |
| HC | Hybrid ceramic balls (silicon nitride) for superior high-speed performance and reduced weight |
| P4A | Super precision tolerance class exceeding ABEC 7 standards for exceptional running accuracy |
71914 FEGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with ceramic balls significantly reduces centrifugal forces, enabling higher limiting speeds while providing electrical insulation properties and extended lubrication life.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional running accuracy and minimal vibration for precision applications.
Optimized Cage Design: The phenolic cage (FE designation) offers excellent high-speed capability with reduced friction and weight, contributing to the bearing's 28,000 rpm limiting speed.
Universal Matching Capability: As part of the SU universal match series, these bearings can be paired in any combination to achieve precise preload settings without selective matching.
Enhanced Load Capacity: With a dynamic load rating of 4860 lbf and static load rating of 3600 lbf, the bearing delivers reliable performance under combined loading conditions.
