7016 FEGA/HCP4A Bearing Product Overview & Core Advantages
The 7016 FEGA/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered to accommodate combined radial and axial loads simultaneously, this bearing features a universal matching design (SU) allowing for precise preload control when mounted in sets. Its ceramic balls and P4A super-precision tolerance deliver superior rotational accuracy, reduced thermal expansion, and extended service life in demanding operational environments.

7016 FEGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with silicon nitride ceramic balls provides significant performance advantages including reduced friction, higher limiting speeds, and electrical insulation properties. This construction minimizes heat generation and extends lubrication life.
Precision Engineering: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, making it ideal for high-speed applications requiring exceptional rotational accuracy. The 18° contact angle optimizes axial load capacity while maintaining good radial load performance.
High-Speed Capability: The phenolic resin cage with steel reinforcement enables operation at 28,000 rpm limiting speed, while the hybrid construction reduces centrifugal forces on the balls at high rotational velocities.
Universal Matching Design: As part of a universally matchable set, these bearings can be arranged in various configurations (back-to-back, face-to-face, or tandem) to achieve specific preload and stiffness requirements without selective matching.
