7022 CB/P4A Bearing Product Overview & Core Advantages
The 7022 CB/P4A is a single-row angular contact ball bearing designed for applications demanding high precision and superior performance. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to accommodate combined loads—significant radial loads and substantial axial loads in one direction. Its key advantages include high rigidity and high-speed capability, supported by a phenolic cage and precision-ground components. The bearing is pre-lubricated and features an open design, making it ideal for high-reliability systems where controlled lubrication is managed externally.
7022 CB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Basic bearing designation indicating the bore diameter (110 mm) and standard dimensions. |
| CB | Specifies a specific contact angle (15°) and internal design for optimized axial load capacity. |
| P4A | Denotes a high-precision tolerance class (P4/ABEC-7) with enhanced running accuracy. |
7022 CB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row design with a 15° contact angle provides excellent resistance to combined (radial and axial) loads, ensuring stable operation under demanding conditions.
- High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, enabling smooth operation at limiting speeds up to 16,000 rpm.
- Precision Engineering: Manufactured to P4 tolerance with tightly controlled bore and outside diameter tolerances, resulting in minimal runout and vibration for high-accuracy applications.
- Optimized Lubrication: Pre-lubricated and designed for external lubrication systems, allowing for customized grease or oil selection to match specific temperature range (-30°C to 110°C) and speed requirements.
7022 CB/P4A Bearing Typical Application Areas
This precision angular contact bearing is commonly specified in:
- Machine Tool Spindles
- High-Speed Motors & Spindles
- Precision Grinding Equipment
