7022 FE/P4A Bearing Product Overview & Core Advantages
The 7022 FE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing delivers superior running precision. Its key advantage lies in its ability to accommodate high combined loads—significant radial loads combined with axial loads in one direction. The phenolic cage and optimized internal geometry contribute to stable high-speed performance, making it an ideal component for high-precision, high-reliability machinery.
7022 FE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Basic bearing series and size designation (Bore: 110 mm, OD: 170 mm, Width: 28 mm). |
| FE | Indicates a specific internal design with a contact angle of 18°, optimized for axial load capacity. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
7022 FE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design, combined with P4A precision tolerances and a 18° contact angle, provides high system rigidity and exceptional running accuracy for precise positioning applications.
- Superior Load Capacity: Engineered to handle high dynamic and static radial loads (10,530 lbf / 9,900 lbf) as well as substantial one-direction axial loads, making it suitable for combined load conditions.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures lower centrifugal forces and reduced friction, enabling a high limiting speed of 16,250 rpm. The open design facilitates efficient lubrication management.
- Pre-Lubricated & Durable: Supplied with lubrication, the bearing is ready for immediate use within a wide operating temperature range of -30°C to 110°C. The chrome steel rings and balls ensure long service life and high durability.
