7022 CDGC/P4A Bearing Product Overview & Core Advantages
The 7022 CDGC/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Positioned in the P4A super-precision tolerance class, it delivers superior running accuracy for demanding machinery. Its 15° contact angle is optimized to support significant combined loads—handling both radial and axial loads simultaneously. Manufactured with Chrome Steel rings and balls, and featuring a lightweight Phenolic cage, this bearing is designed for high-speed operation up to 10,000 rpm. The Moderate preload (Class C) ensures consistent performance and minimal deflection under operational stresses, making it ideal for applications where precision and reliability are paramount.
7022 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
- 7022: Basic model number indicating a 110 mm bore and 170 mm outside diameter.
- C: Denotes a 15° contact angle, optimized for combined radial and axial loads.
- DG: Indicates a Universal Matchable (SU) bearing, supplied in a set of 3 for precise preload arrangement.
- C: Specifies a Moderate preload (Class C) for enhanced rigidity.
- P4A: Signifies the super-precision tolerance class, exceeding ABEC 7 standards for exceptional running accuracy.
7022 CDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design with a 15° contact angle and Moderate preload (Class C) provides excellent stiffness, minimizing axial and radial runout under load for superior positioning accuracy.
- Superior Load Capacity: Engineered to handle combined radial and axial loads efficiently, with a dynamic load rating of 24,975 lbf and static load rating of 24,300 lbf, ensuring reliable performance in demanding conditions.
- Optimized High-Speed Performance: The lightweight Phenolic cage reduces centrifugal forces, while the precision-ground Chrome Steel components and optimized internal geometry enable stable operation at limiting speeds of 10,000 rpm.
- Universal Matching Capability: As a Universal Matchable (SU) bearing supplied in a set of 3, it allows for flexible mounting configurations (DB, DF, DT) to achieve desired preload and rigidity without selective assembly.
