S7016 ACE/P4A Bearing Product Overview & Core Advantages
The S7016 ACE/P4A is a metric single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Its defining feature is the 25° contact angle and P4 (ABEC-7) tolerance class, making it ideal for managing combined radial and axial loads in one direction. The bearing is pre-lubricated and sealed, offering a compact design and ready-to-install convenience for high-reliability machinery.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| ACE | Specific internal design with a 25° contact angle and optimized internal geometry for high performance. |
| P4A | Indicates a P4 (ABEC-7) tolerance class, signifying very high dimensional and running accuracy for precision applications. |
S7016 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 25° contact angle provides high rigidity against combined loads. Manufactured to P4 tolerance standards, it ensures minimal runout and superior rotational accuracy for high-speed spindles.
- Superior Load Capacity: Engineered to support significant combined radial and axial loads simultaneously. With a dynamic load rating of 7312 lbf and a static load rating of 5962 lbf, it delivers reliable performance under demanding conditions.
- Optimized High-Speed Performance: The phenolic resin cage offers low weight and excellent high-speed stability, contributing to the high limiting speed of 13,700 rpm. The optimized internal geometry further enhances high-speed capability.
- Sealed and Pre-Lubricated for Longevity: The integral seals protect against contamination, while the factory-applied lubrication ensures consistent performance and a long service life, making it a low-maintenance solution.
S7016 ACE/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Gearboxes
- High-Frequency Motors and Spindles
- Medical and Dental Equipment
- Robotic Arms and Precision Actuators
