S71906 CDTP/P4B Bearing Product Overview & Core Advantages
The S71906 CDTP/P4B is a super-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, it is optimized to support combined loads, primarily handling high radial loads and substantial thrust loads in one direction. Its P4 (ABEC-7) tolerance class ensures minimal runout and vibration, making it ideal for high-reliability, high-precision spindles and machinery. The bearing comes preloaded and lubricated from the factory, simplifying installation and ensuring immediate, optimal performance.
S71906 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7 | Series designation for high-precision angular contact ball bearings. |
| 1906 | Bore size code (30 mm) and series dimension. |
| C | Specifies a 15° contact angle. |
| D | Indicates a high-capacity internal design with more and/or larger balls. |
| T | Identifies the cage material as phenolic resin, suitable for high speeds. |
| P | Signifies that the bearing is supplied with a preload. |
| P4B | Denotes the tolerance class P4 (ABEC-7) with specific running accuracy requirements. |
S71906 CDTP/P4B Bearing Structural Features & Performance Benefits
- High-Speed Capability: The lightweight phenolic resin cage (code T) reduces centrifugal forces, enabling a high limiting speed of 32,000 rpm. This, combined with the optimized internal geometry, ensures stable operation at high rotational velocities.
- Enhanced Load Capacity: The high-capacity "D" design incorporates a larger ball diameter (4.762 mm) and a greater ball quantity (20), significantly boosting the radial dynamic load rating (1609 lbf) and static load rating (1024 lbf).
- Rigidity and Precision: The 15° contact angle provides excellent resistance to deflection under thrust loads, enhancing system rigidity. Manufactured to P4 precision tolerances, the bearing guarantees minimal runout for superior positioning accuracy.
- Optimized for Immediate Use: The bearing is supplied preloaded, which eliminates internal clearance and increases stiffness, and is factory-lubricated, ensuring it is ready for immediate installation and operation.
S71906 CDTP/P4B Bearing Typical Application Areas
This precision angular contact ball bearing is engineered for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Medical Equipment: Dental handpieces and small high-speed centrifuges.
- Robotics: High-accuracy joints and arm actuators.
