| Code Segment | Technical Meaning |
|---|---|
| 7222 | Basic bearing series; 110 mm bore, 200 mm OD, 76 mm width |
| ACD | 25° contact angle design, optimized for high axial load capacity |
| P4A | High-precision tolerance class exceeding ABEC 7/ISO P4 standards |
| DGC | Universal matchable pair (SU arrangement) with moderate preload (Class C) |
7222 ACD/P4ADGC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and 25° contact angle provide high radial and axial stiffness, enabling stable operation under combined loads.
- Precision & Speed Performance: Manufactured to P4A tolerance class with a phenolic cage, the bearing achieves a high limiting speed of 16,250 rpm while maintaining minimal vibration and heat generation.
- Optimized Universal Matching: As a universal matchable (SU) pair with moderate preload, it simplifies installation and ensures consistent, pre-determined operational performance without additional adjustment.
- Durable Material Construction: Made from chrome steel for rings and balls, it offers high fatigue resistance and longevity in continuous operation within a temperature range of -30°C to 110°C.
