S7016 CD/P4A Bearing Product Overview & Core Advantages
The S7016 CD/P4A is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, ensuring minimal axial and radial play for superior system stability. Its P4 (ABEC-7) tolerance class guarantees high running accuracy, making it ideal for high-speed spindles and other precision machinery where reliable performance under combined loads is critical.
S7016 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7016 | Basic bearing designation (80mm bore, 125mm OD, 22mm width). |
| C | 15° nominal contact angle. |
| D | High preload designation for maximum rigidity. |
| P4A | P4 (ABEC-7) tolerance class with specific accuracy requirements. |
S7016 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The combination of a 15° contact angle and a high preload (D) provides exceptional stiffness, minimizing deflection under load for superior positioning accuracy. The P4 tolerance ensures consistent, high-precision operation.
- Optimized Load Capacity: Engineered to support significant combined radial and axial loads simultaneously, making it suitable for complex loading conditions.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 10,000 rpm. The bearing is pre-lubricated for immediate high-speed operation.
- Sealed & Ready-to-Use: As a sealed bearing, it is protected from contamination and comes lubricated for life, reducing maintenance requirements and ensuring long-term reliability.
