7022 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7022 CD/P4ADGB is a precision angular contact ball bearing manufactured to ABEC 7 / P4A tolerance class, delivering exceptional rotational accuracy and performance stability. Engineered with a 15° contact angle and Universal Matchable (SU) design, it is optimized to handle combined loads—significant radial loads alongside axial loads in one direction. Its light preload (Class B) minimizes deflection under operational stresses, making it an ideal solution for high-precision, high-rigidity applications such as machine tool spindles and high-speed industrial equipment.
7022 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Standard bearing series, with 110 mm bore, 170 mm OD, 56 mm width. |
| CD | Universal Matchable (SU) bearing designed for duplex mounting in any configuration (DB, DF, DT). |
| P4A | High precision tolerance class (equivalent to ABEC 7) with enhanced dimensional and running accuracy. |
| DGB | Indicates a matched set of two bearings supplied with light preload for immediate installation. |
7022 CD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design and phenolic cage provide high rigidity and stable operation under combined radial and axial loads. With a dynamic load rating of 40,050 lbf and static load rating of 48,600 lbf, it ensures reliable performance in demanding conditions.
Precision & Speed: Manufactured to P4A tolerance with a 15° contact angle, this bearing supports high-speed operation up to 10,000 rpm. The phenolic cage contributes to lower friction and higher limiting speeds.
Material & Lubrication: Constructed from chrome steel rings and balls, it offers high wear resistance and durability. The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
7022 CD/P4ADGB Bearing Typical Application Areas
- Machine Tool Spindles – High-precision machining centers and lathes requiring rigidity and accuracy.
- High-Speed Industrial Pumps & Compressors – For handling combined loads at elevated speeds.
- Precision Grinding Spindles – Applications demanding minimal runout and high rotational precision.
