S7022 CD/P4ADGB Bearing Product Overview & Core Advantages
The S7022 CD/P4ADGB is a precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This P4A tolerance class bearing is designed to accommodate combined loads, simultaneously handling significant radial loads and bidirectional axial loads. Its compact double-row design offers high rigidity and stable rotational characteristics, making it ideal for high-speed spindles and precision machinery. Preloaded as Light / Class B and pre-lubricated with grease, it delivers optimized performance right from installation.
S7022 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Universal Matchable (SU) design. Two bearings are optimally paired for a specific preload and can be universally mounted in any combination. |
| P4A | Indicates a high-precision tolerance class with running accuracy requirements stricter than ABEC 7/ISO P4, ensuring minimal runout and vibration. |
| DGB | The bearing is sealed on both sides, providing robust protection against contamination. It is pre-lubricated with grease suitable for the specified temperature range. |
S7022 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design, with a 15° contact angle, provides superior radial and axial stiffness. It supports a high dynamic load rating of 40,050 lbf and a static load rating of 48,600 lbf, enabling reliable operation under combined loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance standards with a phenolic cage, this bearing ensures smooth operation and contributes to a high limiting speed of 16,000 rpm. The precision-ground chrome steel components minimize friction and heat generation.
- Sealed & Ready-to-Use: The integral seals effectively exclude contaminants and retain lubricant. Pre-lubricated with grease, the bearing offers a long service life and is effectively maintenance-free within its operating temperature range of -30°C to 110°C.
- Universal Matchability: The Universal Matchable (SU) feature allows for simplified mounting and optimal preload achievement when two bearings are paired, enhancing system performance and simplifying inventory.
