7016 ACE/P4A Bearing Product Overview & Core Advantages
The 7016 ACE/P4A is a single row angular contact ball bearing designed for applications demanding high precision and superior performance under combined loads. Engineered to a P4 (ABEC-7) tolerance class, it offers exceptional running accuracy. Its key advantage is the ability to accommodate significant axial loads in one direction, in addition to radial loads, making it ideal for high-speed spindles and precision machinery where high rigidity and precise shaft positioning are critical. The phenolic cage and optimized internal geometry contribute to its high-speed capabilities.

| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series, indicating a metric 80mm bore, 125mm OD, and 22mm width. |
| ACE | Indicates a 25° contact angle and that the bearing is supplied lubricated. |
| P4A | Specifies the tolerance class P4 (ABEC-7), denoting very high precision levels for dimensional and running accuracy. |
7016 ACE/P4A Bearing Structural Features & Performance Benefits
Optimized Contact Angle & Rigidity: The 25° contact angle is engineered to efficiently support combined (radial and axial) loads, providing high axial rigidity for stable shaft operation.
High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction at high speeds, contributing to the bearing's high limiting speed of 21,000 rpm.
Precision Engineering: Manufactured to P4 (ABEC-7) tolerance standards, this bearing guarantees minimal runout and vibration, which is essential for applications requiring extreme accuracy.
Robust Load Capacity: With a dynamic load rating of 7312 lbf and a static load rating of 5962 lbf, it is built to handle demanding operational conditions reliably.
