S71910 CDTP/P4B Bearing Product Overview & Core Advantages
The S71910 CDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. As a single-row bearing with a 15° contact angle and P4 (ABEC-7) tolerance class, it excels in handling combined radial and axial loads simultaneously. Its preloaded configuration ensures zero operational clearance, providing superior rotational accuracy, high system stiffness, and smooth operation at high speeds, making it ideal for high-precision, high-reliability machinery.
S71910 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S71910 | Basic designation for a high-precision angular contact ball bearing series with a 50mm bore. |
| C | Specifies a 15° contact angle, optimized for high-speed applications requiring a balance of radial and axial load capacity. |
| DT | Indicates a matched pair arrangement in a tandem duplex configuration (two bearings mounted together). |
| P | Denotes that the bearing is preloaded to eliminate internal clearance, enhancing rigidity and rotational precision. |
| P4B | Specifies a P4 (ABEC-7) tolerance class with additional running accuracy requirements, ensuring ultra-precise performance. |
S71910 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The preloaded single-row design with a 15° contact angle provides exceptional system stiffness and minimizes axial and radial runout, which is critical for precision machining and positioning.
- Superior Load Capacity: Engineered to handle combined loads efficiently, with a dynamic load rating of 3038 lbf and a static load rating of 2340 lbf. The angular contact design is particularly effective at sustaining thrust loads in one direction.
- Optimized High-Speed Performance: The phenolic resin cage offers low weight and excellent sliding properties, contributing to a high limiting speed of 17,000 rpm. This makes the bearing suitable for high-speed spindles.
- Premium Materials & Lubrication: Constructed from chrome steel for rings and balls, ensuring high durability and wear resistance. The bearing is pre-lubricated for immediate operation and long service life within its specified temperature range.
S71910 CDTP/P4B Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers, grinding spindles, and CNC lathes requiring high precision and rigidity.
- Precision Rotary Systems: Applications in robotics, optical scanners, and coordinate measuring machines (CMM).
- High-Speed Motors & Drives: Servo motors, spindle drives, and other applications where low vibration and high running accuracy are paramount.
- Medical & Laboratory Equipment: Centrifuges and other precision instruments that demand quiet, reliable, and accurate rotation.
