S7022 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7022 CD/P4ADGA is a precision double row angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. Designed to accommodate combined loads (radial and bidirectional axial loads) simultaneously, this bearing features a P4A tolerance class for superior running accuracy and an extra light preload (Class A) for minimal friction and precise shaft positioning. Its compact design and universal matchable (SU) capability allow for flexible mounting arrangements in high-reliability systems, making it an ideal solution for high-speed and high-precision machinery.
S7022 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| C | 15° Contact Angle | Optimized for handling axial loads and moderate radial loads. |
| D | Double Row Design | Provides high rigidity and increased load-carrying capacity. |
| P4A | High Precision Tolerance Class | Ensures extremely tight dimensional and running accuracy for smooth, quiet operation. |
| DG | Universal Matchable (SU Pair) | Two bearings are supplied as a pre-matched set (SU arrangement) for simplified installation and optimal preload. |
| A | Extra Light Preload | Reduces friction and heat generation, enabling higher speeds and longer service life. |
S7022 CD/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row angular contact design significantly enhances system stiffness, enabling the bearing to support substantial combined loads and moment loads effectively. With a radial dynamic load rating of 40,050 lbf and a static load rating of 48,600 lbf, it is built for demanding applications.
High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 16,000 rpm. The optimized internal geometry and 15° contact angle further support stable operation at elevated speeds.
Precision and Longevity: Manufactured to P4A tolerance class with a bore and OD tolerance of -0.004mm to 0, this bearing guarantees precise shaft runout and positioning. The sealed construction, pre-lubricated with grease, protects against contamination and provides maintenance-free operation within a temperature range of -30°C to 110°C.
