7022 CDTP/P4B Bearing Product Overview & Core Advantages
The 7022 CDTP/P4B is a high-precision angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. As a single-row bearing with a 15° contact angle, it is optimized to support combined loads, handling significant radial loads alongside axial loads in one direction. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other precision machinery. The bearing is preloaded and pre-lubricated, delivering immediate high performance, high stiffness, and reliable operation right from installation.
7022 CDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 7022 | Basic Bearing Number | Defines the standard metric dimensions: 110mm bore, 170mm OD, 28mm width. |
| C | 15° Contact Angle | Optimized for high-speed operation and moderate axial load capacity. |
| D | High Load Capacity Design | Indicates an internal geometry designed for increased dynamic and static load ratings. |
| T | Phenolic (Textile) Cage | The phenolic cage offers low weight, high strength, and excellent performance at high speeds. |
| P | Glass Fiber Reinforced Cage | Further specifies the cage material as glass fiber reinforced phenolic for added durability. |
| P4B | Tolerance Class & Internal Clearance | Denotes a P4 (ABEC-7) precision tolerance and a specific "B" group internal clearance for preload matching. |
7022 CDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance class with a 15° contact angle and supplied preloaded, this bearing provides exceptional system stiffness and minimizes runout, which is critical for machining accuracy.
- Superior Load Capacity: The "D" design and use of chrome steel balls contribute to high dynamic (24,975 lbf) and static (24,300 lbf) load ratings, enabling reliable performance under demanding combined loads.
- Optimized High-Speed Performance: The lightweight, robust phenolic cage (T/P) minimizes centrifugal forces and ensures stable operation, supporting a limiting speed of 7,500 rpm.
- Ready-to-Install Convenience: The bearing is pre-lubricated, simplifying installation and ensuring immediate, reliable performance within its specified temperature range of -30°C to 110°C.
