7206 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7206 CD/P4ADGB is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. As a universal matchable (SU) bearing supplied in a light preload (Class B) duplex set, it excels in handling combined radial and axial loads simultaneously. Its P4A tolerance class ensures ultra-precision performance, making it ideal for high-speed spindles and other critical machinery where minimal runout and high operational reliability are paramount.
7206 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7206 | Basic bearing series, indicating a 30mm bore, 62mm OD, and 32mm width. |
| C | 15° nominal contact angle. |
| D | Indicates the bearing is part of a universal matchable (SU) duplex pair. |
| P4A | Super-precision tolerance class, exceeding ABEC 7/ISO P4 standards for enhanced running accuracy. |
| DGB | Duplex set configuration designation (Back-to-Back arrangement) with light preload (Class B). |
7206 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex set (two bearings) in a back-to-back (DB) arrangement provides superior rigidity and stability, effectively supporting combined loads and moment loads. The 15° contact angle is optimized for substantial axial load capacity.
- Super-Precision Performance: Manufactured to P4A tolerance class, this bearing guarantees minimal radial and axial runout, which is critical for applications requiring extreme positional accuracy and smooth operation.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling a high limiting speed of 71,500 rpm. The open design and factory-applied lubrication facilitate efficient heat dissipation.
- Universal Matchability (SU): As a universal matchable bearing, any two bearings from the same lot can be paired in any duplex configuration (DB, DF, DT) without pre-load loss, offering exceptional flexibility in mounting and application design.
7206 CD/P4ADGB Bearing Typical Application Areas
The 7206 CD/P4ADGB is engineered for the most demanding precision applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Internal and external grinding machines.
- High-Frequency Motors: Spindles for PCB drilling and routing.
- Medical Equipment: High-speed centrifuges and dental handpieces.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and navigation instruments.
