7022 ACDTP/P4B Bearing Product Overview & Core Advantages
The 7022 ACDTP/P4B is a single-row angular contact ball bearing designed for applications requiring high precision and superior rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing excels at handling combined loads—simultaneously supporting significant radial loads and unidirectional axial loads. Its optimized 25° contact angle and phenolic cage contribute to exceptional high-speed performance with a limiting speed of 7,000 rpm. Preloaded and pre-lubricated, it delivers immediate, maintenance-free operation in demanding environments.
7022 ACDTP/P4B Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle for optimal axial load capacity |
| DTP | Preloaded configuration ensuring high rigidity and minimal deflection under load |
| P4B | P4 (ABEC-7) tolerance class with enhanced running accuracy for precision applications |
7022 ACDTP/P4B Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design with preload (DTP) ensures maximum stiffness and positional accuracy, critical for machine tool spindles and precision equipment.
- Superior Load Capacity: With a 25° contact angle and optimized internal geometry, the bearing efficiently handles combined radial and axial loads in one direction.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at high rotational speeds up to 7,000 rpm.
- Precision Engineering: Manufactured to P4 (ABEC-7) tolerance class with tight dimensional control (bore tolerance: -0.008mm to 0), ensuring consistent performance in precision applications.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, providing excellent wear resistance and long service life.
