S7022 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7022 ACDGB/P4A is a high-precision double row angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to simultaneously accommodate combined loads (radial and bidirectional axial loads), its compact design offers a space-saving solution. The bearing features a light preload (Class B) for enhanced rotational accuracy and stiffness, making it ideal for high-speed, high-reliability machinery. Its sealed construction and pre-lubrication ensure long-term performance with minimal maintenance.
S7022 ACDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
- S7022: Basic model number denoting a double row angular contact ball bearing with a 110mm bore and 170mm outside diameter.
- ACD: Designates the specific internal geometry and contact angle (25°).
- GB: Indicates a light preload (Class B).
- P4A: Specifies a super-precision tolerance class, exceeding standard P4 levels for exceptional running accuracy.
S7022 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The double row design provides superior radial and axial rigidity, enabling stable operation under combined loads. The 25° contact angle is optimized for supporting significant axial loads in both directions.
Precision and Speed: Manufactured to P4A super-precision tolerances, the bearing ensures minimal runout and vibration. The phenolic resin cage contributes to smooth operation at high speeds, with a limiting speed of 16,000 rpm. The bearing is universally matchable (SU), allowing for precise preload control when mounted in sets.
Durability and Maintenance: Constructed from chrome steel for both rings and balls, the bearing offers high durability. The sealed design and factory-applied grease lubrication protect against contamination and provide reliable operation within a temperature range of -30°C to 110°C, promoting a long, maintenance-free service life.
