7016 CE/P4A Bearing Product Overview & Core Advantages
The 7016 CE/P4A is a single-row angular contact ball bearing engineered for applications demanding exceptional precision and high-speed performance. As a P4 (ABEC-7) tolerance class bearing, it guarantees superior running accuracy. Its primary advantage lies in its ability to accommodate combined loads—simultaneously handling significant radial loads and axial loads in one direction. The 15° contact angle is optimized for high-speed operation, while the phenolic cage contributes to smooth performance. This bearing is preloaded and comes pre-lubricated, making it an ideal, ready-to-install solution for high-rigidity and high-reliability systems.
7016 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7016 | Basic bearing series and size designation (80mm bore, 125mm OD, 22mm width). |
| C | Specifies a 15° contact angle, optimized for high-speed applications. |
| E | Indicates an optimized internal design, often for higher load capacity. |
| P4 | Denotes a high-precision tolerance class (equivalent to ABEC-7). |
| A | Signifies that the bearing has a specific preload applied for increased rigidity. |
7016 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row angular contact design, combined with a P4 tolerance class and applied preload, provides exceptional shaft positioning accuracy and system stiffness, minimizing deflection under load.
- Superior Load Capacity: Engineered to support combined loads effectively. With a dynamic load rating of 7605 lbf and a static load rating of 6300 lbf, it reliably handles both radial and one-direction axial forces.
- Optimized High-Speed Performance: The 15° contact angle and lightweight phenolic resin cage reduce centrifugal forces and friction, enabling a high limiting speed of 24,000 rpm. This makes it an excellent high-speed bearing.
- Durable Construction: Manufactured from chrome steel for both rings and balls, ensuring high durability and long service life under demanding conditions.
