S7016 CEGC/P4A Bearing Product Overview & Core Advantages
The S7016 CEGC/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial loads), its single-row design with a 15° contact angle provides optimal performance in high-speed scenarios. Manufactured to the exacting P4A tolerance class, this bearing ensures minimal runout and superior rotational accuracy. Its universal matchable (SU) designation allows for flexible mounting in preloaded pairs, delivering enhanced system stiffness and operational reliability in compact installations.

| C | 15° nominal contact angle. |
| E | Optimized internal design for high performance. |
| GC | Specific internal clearance and preload grouping for universal matching. |
| P4A | High precision tolerance class exceeding ABEC 7 standards, ensuring extremely tight dimensional and running accuracy. |
S7016 CEGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The phenolic cage and precision-ground chrome steel components provide a robust structure capable of withstanding significant radial dynamic load ratings of 7605 lbf and static load ratings of 6300 lbf.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, enabling a high limiting speed of 28,000 rpm. The 15° contact angle is ideal for applications requiring high-speed operation with axial loads.
- Precision Engineering: Manufactured to P4A tolerance class with tight bore, outer diameter, and width tolerances, this bearing guarantees minimal vibration and exceptional running accuracy for precision spindle applications.
- Universal Matching Capability (SU): Bearings are supplied with selective tolerances, allowing them to be mounted in pairs (back-to-back, face-to-face, or tandem) without the need for selective shimming, simplifying installation and ensuring optimal preload.
S7016 CEGC/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery where precision and speed are critical. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, high-frequency motor spindles.
- Industrial Pumps & Compressors: For handling axial and radial loads in demanding fluid systems.
- Robotics and Automation: High-accuracy rotary joints and arm assemblies.
