S7020 CDTP/P4B Bearing Product Overview & Core Advantages
The S7020 CDTP/P4B is a single-row angular contact ball bearing engineered for precision applications requiring exceptional rotational accuracy and high-speed capability. Manufactured to P4 (ABEC-7) tolerance class, this bearing is preloaded and pre-lubricated, delivering superior running accuracy, high system rigidity, and reliable performance. Its design is optimized to handle combined loads, with a 15° contact angle providing excellent axial load capacity in one direction. The combination of a phenolic cage and high-grade lubricant enables outstanding high-speed performance, making it ideal for demanding, precision-driven machinery.
S7020 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| C | Specifies a 15° contact angle, optimized for high-speed applications and axial load capacity. |
| D | Indicates a high-precision phenolic resin cage for reduced weight, superior strength, and enhanced high-speed performance. |
| TP | Signifies that the bearing is preloaded, ensuring minimal axial and radial play for high rigidity and precise shaft positioning. |
| P4B | Denotes the P4 (ABEC-7) tolerance class, guaranteeing extremely tight dimensional and running accuracy for precision applications. |
S7020 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design combined with preload ensures high system rigidity and precise rotational accuracy, critical for machine tool spindles and other high-precision equipment.
- Superior Load Capacity: Engineered with a 15° contact angle and high-grade chrome steel components, this bearing effectively handles combined radial and substantial one-direction axial loads, with a dynamic load rating of 18,720 lbf.
- Optimized High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 8,500 rpm, reducing centrifugal forces and operational temperatures.
- Sealed & Lubricated for Longevity: As a sealed and pre-lubricated bearing, it is protected from contamination and is ready for immediate installation, offering a long service life within its specified temperature range of -30°C to 110°C.
