7022 CD/P4ADGC Bearing Product Overview & Core Advantages
The 7022 CD/P4ADGC is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-set pair, it is engineered to accommodate combined loads (radial and axial) simultaneously. Its P4A tolerance class ensures ultra-precise dimensions and running accuracy, making it ideal for high-speed and high-reliability spindles and machinery. The moderate preload (Class C) provides optimal stiffness right from installation, reducing deflection and vibration under operational stresses.
7022 CD/P4ADGC 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: 56 mm). |
| CD | Indicates a universal matchable pair of bearings with a 15° contact angle. This arrangement provides high rigidity and can accommodate axial loads in either direction when mounted face-to-face or back-to-back. |
| P4A | Denotes a super-precision tolerance class. This includes very tight limits on bore, outside diameter, width, and running accuracy, which is critical for high-speed and high-precision applications. |
| DGC | Specifies the cage material and lubrication. The phenolic resin cage (D) offers low weight and excellent performance at high speeds. The bearing is pre-lubricated (GC) with a high-performance grease suitable for the specified temperature range. |
7022 CD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The universal matchable (SU) pair, combined with the 15° contact angle and moderate preload, creates a system with superior stiffness. This design effectively handles significant combined radial and axial loads, minimizing shaft deflection and ensuring positional accuracy.
- Super-Precision High-Speed Performance: Manufactured to P4A tolerance standards, this bearing guarantees minimal runout and vibration. The lightweight phenolic cage reduces centrifugal forces, while the optimized internal geometry and pre-lubrication contribute to a high limiting speed of 10,000 rpm, making it a true high-speed bearing.
- Optimized Internal Geometry: With 20 high-precision chrome steel balls of 19.05 mm diameter, the bearing provides a large load-carrying capacity and smooth, quiet operation.
- Ready-to-Install Convenience: The bearing pair is supplied pre-lubricated and universally matchable, simplifying the installation process and ensuring immediate, optimal performance without the need for complex adjustments.
7022 CD/P4ADGC Bearing Typical Application Areas
The 7022 CD/P4ADGC is engineered for the most demanding precision machinery, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Applications requiring extreme accuracy and surface finish quality.
- High-Frequency Motors and Spindles: Where minimal vibration and high rotational speeds are critical.
- Industrial Pumps and Compressors: For reliable performance under combined loads.
- Advanced Robotics and Automation: Precision rotary joints and arms.
