S7008 CDTP/P4B Bearing Product Overview & Core Advantages
The S7008 CDTP/P4B is a precision single-row angular contact ball bearing engineered for high-performance applications. It is designed to accommodate combined loads, primarily handling significant axial loads in one direction while also supporting radial loads. Its key advantages include high rigidity and exceptional running accuracy due to its P4 (ABEC-7) tolerance class. Pre-loaded and pre-lubricated, this bearing is optimized for high-speed operation up to 20,000 rpm, making it a compact and reliable solution for demanding machinery.
S7008 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7008 | Basic bearing series and size designation (40mm bore, 68mm OD). |
| C | Specific internal design and 15° contact angle. |
| D | Indicates a matched arrangement (in this case, a single bearing supplied pre-loaded). |
| T | Referencing the phenolic (synthetic resin) cage. |
| P | Indicates the bearing is pre-lubricated. |
| P4B | Specifies the P4 tolerance class (equivalent to ABEC-7), denoting very high precision. |
S7008 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to a P4 tolerance class with a 15° contact angle, this bearing provides superior running accuracy and stiffness, essential for minimizing deflection under load.
- Optimized Load Capacity: The angular contact design is engineered to handle combined radial and axial loads simultaneously. With a dynamic load rating of 3780 lbf, it offers reliable performance in demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, while the pre-lubrication ensures smooth operation, enabling a high limiting speed of 20,000 rpm.
- Sealed and Ready-to-Use: As a sealed unit, it is protected from contamination. Being pre-lubricated and pre-loaded, it is a maintenance-free solution that simplifies installation and ensures long-term reliability.
S7008 CDTP/P4B Bearing Typical Application Areas
This precision bearing is ideally suited for applications requiring high speed, rigidity, and accuracy, such as:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Robotic Arm Joints and Drives
