S7022 ACD/P4A Bearing Product Overview & Core Advantages
The S7022 ACD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a single-row bearing with a 25° contact angle and P4 (ABEC-7) tolerance class, it is engineered to handle combined loads—significant radial loads alongside high unidirectional axial loads. Its preload availability ensures minimal axial and radial play, resulting in superior system stiffness, precise shaft positioning, and smooth operation at high speeds. This bearing is pre-lubricated and sealed, making it a robust, ready-to-install solution for high-performance machinery.
S7022 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Indicates a 25° contact angle and optimized internal geometry for high axial load capacity and rigidity. |
| P4A | Specifies the P4 (ABEC-7) tolerance class, denoting very high precision levels for running accuracy and dimensional stability. |
S7022 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 25° contact angle and the option for preload delivers high system stiffness, reducing deflection under load and ensuring exceptional running accuracy.
- Superior Load Capacity: Engineered to support combined loads effectively, with a high dynamic and static load rating of 23,400 lbf, making it suitable for applications with significant radial and axial forces.
- Optimized High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 7,000 rpm. The chrome steel construction ensures dimensional stability under thermal and mechanical stress.
- Sealed and Lubricated for Longevity: As a sealed and pre-lubricated bearing, it is protected from contamination and is designed for long-term, maintenance-free operation within a wide temperature range of -30°C to 110°C.
