7007 CD/P4ATBTB Bearing Product Overview & Core Advantages
The 7007 CD/P4ATBTB is a precision angular contact ball bearing configured as a triplex back-to-back (TBT) matched set. This arrangement delivers exceptional system rigidity and is engineered to handle complex combined loads, including high radial loads and significant axial loads in both directions. Manufactured to the stringent P4A tolerance class, it guarantees superior running accuracy, making it ideal for demanding applications requiring high-speed operation and precise rotational performance.
7007 CD/P4ATBTB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Indicates a 15° contact angle and specific internal design optimized for high rigidity and speed. |
| P4A | Denotes an ultra-precision tolerance class with enhanced dimensional and running accuracy beyond standard P4. |
| TBT | Signifies a Triplex Back-to-Back matched set of three bearings, providing maximum system rigidity and moment load capacity. |
7007 CD/P4ATBTB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The triplex back-to-back (TBT) configuration creates an extremely rigid bearing system capable of withstanding heavy combined radial and axial loads, as well as high moment loads. The 15° contact angle is optimized for this high-rigidity setup.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with a phenolic cage, this bearing ensures minimal vibration and excellent stability at high rotational speeds, with a limiting speed of 56,000 rpm.
- Optimized Material & Design: Constructed from chrome steel for both rings and balls, ensuring high durability and fatigue life. The open design, pre-lubricated for immediate use, allows for optimal lubrication management in the application.
7007 CD/P4ATBTB Bearing Typical Application Areas
This precision triplex bearing set is specifically designed for high-performance machinery requiring ultimate rigidity and accuracy, including:
- Machine Tool Spindles (High-speed milling, grinding)
- Precision Gearboxes
- High-Frequency Spindles
- Industrial Pumps and Compressors
