7022 CD/P4ATGA Bearing Product Overview & Core Advantages
The 7022 CD/P4ATGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Manufactured to P4A tolerance class, this bearing is engineered to handle combined loads with high reliability. Its universal matchable (SU) design allows for flexible mounting arrangements in sets, while the extra light preload (Class A) ensures smooth, precise operation with minimal friction. This makes it an ideal solution for high-speed, high-precision machinery where uncompromising performance is critical.
7022 CD/P4ATGA Bearing Model Code Explained, Specifications & Naming Convention
| 7022 | Basic designation indicating a 110 mm bore and 170 mm outside diameter. |
| CD | Specifies a 15° contact angle and optimized internal design for high-speed operation. |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
| TGA | Indicates the use of a phenolic resin cage, contributing to lower friction and suitability for high-speed applications. |
7022 CD/P4ATGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and robust construction enable the bearing to support significant combined radial and axial loads (Dynamic: 53,550 lbf, Static: 73,125 lbf), ensuring stable operation under demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic cage (TGA) reduces centrifugal forces and maintains stability, enabling a limiting speed of 10,000 rpm. The optimized internal geometry further enhances high-speed capability.
- Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing guarantees exceptional running accuracy and minimal vibration.
- Universal Matching Capability (SU): Designed to be used in pre-adjusted sets of three, these bearings simplify installation and provide a pre-defined, consistent preload for optimal system performance.
7022 CD/P4ATGA Bearing Typical Application Areas
- Machine Tool Spindles: For high-precision milling, grinding, and turning centers requiring extreme accuracy and rigidity.
- High-Speed Machining Centers: Ideal for spindles operating at very high rotational speeds.
- Precision Gearboxes: Used in applications where low friction and high positional accuracy are paramount.
- Industrial Pumps and Compressors: Suitable for high-performance rotors handling significant axial and radial forces.
