S71907 CDTP/P4B Bearing Product Overview & Core Advantages
The S71907 CDTP/P4B is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 15° contact angle, it efficiently handles combined loads (radial and axial) in one direction. Its P4 (ABEC-7) tolerance class ensures ultra-precise running, making it ideal for high-speed spindles and precision machinery. The bearing comes preloaded and pre-lubricated, delivering immediate high performance, superior running accuracy, and excellent operational stability right out of the box.
S71907 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| C | 15° Contact Angle | Optimized for high-speed operation and moderate axial loads. |
| D | High-Precision Machined Brass Cage | Provides high strength and excellent guidance at very high speeds. |
| T | Tapered Bore | Allows for precise adjustment of internal clearance or preload via an adapter sleeve or withdrawal sleeve. |
| P | Glass Fiber Reinforced PEEK Cage | Offers low weight, high strength, and excellent performance in demanding lubrication conditions. |
| P4B | Tolerance Class P4 (ABEC-7) with Enhanced Running Accuracy | Guarantees ultra-precise dimensions and minimal runout for superior performance in high-speed, high-precision applications. |
S71907 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance class with a tapered bore, this bearing achieves exceptional running accuracy and system rigidity, which is critical for machine tool spindles.
- Superior High-Speed Capability: The combination of a 15° contact angle and a high-strength phenolic resin cage enables stable operation at the high limiting speed of 26,000 rpm.
- Optimized Load Capacity: The single-row angular contact design is engineered to support significant combined loads, with a dynamic load rating of 2194 lbf and a static load rating of 1474 lbf.
- Preload & Sealing: Supplied as a preloaded unit, it eliminates internal clearance for immediate high stiffness and accuracy. The sealed design protects against contamination and retains lubrication, enhancing service life.
- Premium Materials: Components made from chrome steel (rings and balls) provide high wear resistance and durability, ensuring long-term reliability.
