7016 CEGA/HCP4A Bearing Product Overview & Core Advantages
The 7016 CEGA/HCP4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and performance. Engineered to accommodate combined loads (radial and axial), this bearing features a 15° contact angle and is supplied as part of a universally matchable set, enabling precise preload configuration. Its construction with ceramic balls and a phenolic cage contributes to superior high-speed capability and reduced weight, making it ideal for high-reliability, high-rigidity spindle applications.

| 7016 | Standard bearing series designation (80mm bore, 125mm OD, 22mm width) |
| CE | Contact angle of 15° |
| GA | Universal matching bearing designation (can be paired in any combination) |
| HCP4A | Precision class P4A with phenolic cage and ceramic balls |
7016 CEGA/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity & Precision: Manufactured to P4A tolerance class with extremely tight dimensional tolerances, this bearing provides stable, high-rigidity support for precision machinery.
Enhanced High-Speed Performance: The combination of a lightweight phenolic cage and ceramic balls significantly reduces centrifugal forces, enabling operation at limiting speeds up to 28,000 rpm.
Superior Load Capacity: The 15° contact angle is optimized to handle substantial axial loads in one direction while simultaneously supporting radial loads.
Universal Matching Capability: Supplied as a set of 4 bearings that are universally matchable (SU), allowing for flexible arrangement configurations (DB, DF, DT) to achieve the required preload and system stiffness.
