7222 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7222 CD/P4ADGB 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 set of two, it is engineered to accommodate combined loads (radial and axial) simultaneously. Its P4A tolerance class and light preload (Class B) ensure high running accuracy and smooth operation, making it ideal for high-speed, high-precision machinery where reliability is paramount.
7222 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
The model number 7222 CD/P4ADGB is decoded as follows:
- 7222: Basic bearing designation (Bore: 110 mm, OD: 200 mm, Width: 76 mm)
- C: 15° contact angle
- D: Indicates a Universal Matchable (SU) bearing designed to be paired in a set
- P4A: High precision tolerance class exceeding ABEC 7/ISO P4, with specific running accuracy requirements
- DGB: Combination code indicating Universal Matchable (SU) bearings supplied as a matched set of 2 with a specific preload and axial clearance
7222 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and Universal Matchable (SU) pairing enable the bearing set to withstand significant combined radial and axial loads from both directions, providing stable and rigid support for shafts.
- Precision & High-Speed Performance: Manufactured to a P4A tolerance class, this bearing guarantees minimal runout and vibration. The phenolic resin cage and optimized internal geometry contribute to stable operation at high speeds, with a limiting speed of 16,000 rpm.
- Optimized for Matched Sets: The Universal Matchable (SU) designation and DGB combination code mean the two bearings are factory-selected and pre-set to provide a defined light preload (Class B), ensuring immediate optimal performance upon installation without additional adjustments.
- Durable Construction: Components made from chrome steel for both rings and balls offer high wear resistance and durability, suitable for a wide temperature range from -30°C to 110°C.
7222 CD/P4ADGB Bearing Typical Application Areas
