S7010 CB/P4A Bearing Product Overview & Core Advantages
The S7010 CB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a single-row bearing with a 15° contact angle and available preload, it is engineered to handle combined loads—primarily thrust loads in one direction with significant radial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-reliability, high-precision machinery. The phenolic cage and factory-applied lubrication contribute to its smooth operation at limiting speeds up to 24,000 rpm.
S7010 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| CB | Specific internal clearance and preload designation | Optimizes bearing rigidity and running accuracy for the application. |
| P4A | Dimensional and running accuracy to P4 (ABEC-7) tolerance class | Ensures ultra-precise operation, minimal vibration, and superior performance in high-speed spindles. |
S7010 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Running Accuracy: The combination of a 15° contact angle and applied preload provides high axial and radial stiffness, minimizing deflection under load for exceptional positional accuracy.
- Optimized High-Speed Performance: The lightweight phenolic resin cage offers excellent strength and guidance at high speeds, while the pre-lubrication reduces friction and heat generation, enabling a high limiting speed of 24,000 rpm.
- Superior Load Capacity: With a dynamic load rating of 2239 lbf and a static load rating of 1755 lbf, this bearing is capable of handling significant combined loads.
- Sealed and Lubricated for Life: The sealed design and factory-applied grease protect against contamination and provide long-term, maintenance-free operation within the specified temperature range of -30°C to 110°C.
S7010 CB/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, high-frequency motors, and dental handpieces.
- Robotics: High-accuracy joints and servo motors.
- Pumps and Compressors: Applications requiring high-speed and reliable thrust capacity.
