7022 CDGB/P4A Bearing Product Overview & Core Advantages
The 7022 CDGB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Operating under the stringent P4A tolerance class, this bearing is engineered to handle combined loads with superior performance. Its 15° contact angle and Universal Matchable (SU) design make it ideal for preloaded arrangements in high-speed spindles and precision machinery, ensuring reliable operation and long service life.
7022 CDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7022 | Standard bearing series designation, indicating bore diameter of 110 mm and outside diameter of 170 mm. |
| C | Specifies a 15° contact angle, optimized for high-speed applications and axial load capacity. |
| D | Indicates a Light preload (Class B), providing enhanced rigidity and reduced deflection in operation. |
| GB | Signifies the bearing is part of a Universal Matchable (SU) set, allowing for precise preloading when mounted with other bearings from the same group. |
| P4A | Denotes the tolerance class, representing extremely high precision levels for runout and dimensional accuracy. |
7022 CDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design and light preload work in tandem to deliver superior system stiffness, effectively handling both radial and axial loads. With a dynamic load rating of 24,975 lbf and static load rating of 24,300 lbf, it offers robust performance under demanding conditions.
High-Speed Performance: Featuring a lightweight phenolic cage and optimized internal geometry, this bearing achieves a limiting speed of 10,000 rpm. The 15° contact angle further enhances its suitability for high-speed spindle applications.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls on the bore diameter, outside diameter, and width, this bearing ensures minimal runout and vibration for ultra-precise rotational motion.
Matched Set Compatibility: As a Universal Matchable (SU) bearing, it can be supplied in sets of three for simplified installation and optimal preload configuration in complex bearing arrangements.
