7200 CD/P4ADGB Bearing Product Overview & Core Advantages
The 7200 CD/P4ADGB is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing supplied in a pre-loaded duplex set, it delivers superior rigidity and can accommodate combined loads (radial and axial) simultaneously. Manufactured to P4A tolerance class with a 15° contact angle and light preload (Class B), it is engineered for high-precision spindles and other demanding machinery where minimal runout and high reliability are critical.
7200 CD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7200 | Basic bearing series, defining the boundary dimensions (30mm OD, 10mm Bore, 18mm Width). |
| C | Designates a 15° contact angle. |
| D | Indicates the bearing is part of a universal matchable (SU) duplex set. |
| P4A | Specifies the high-precision tolerance class, exceeding ABEC-7 standards. |
| DB | Indicates a back-to-back mounting arrangement of the duplex set. |
7200 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a stiff bearing system that effectively resists moment loads. This configuration, combined with the 15° contact angle, provides excellent capability for handling combined radial and axial loads.
- Superior High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to the high limiting speed of 185,000 rpm. The open design allows for efficient lubrication management.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control on the bore diameter, outside diameter, and width, ensuring minimal runout and vibration for ultra-precise applications.
- Universal Matchability (SU): Bearings are universally matchable, allowing any two bearings to be paired in a back-to-back (DB) or face-to-face (DF) arrangement without selective mounting, simplifying installation and inventory.
7200 CD/P4ADGB Bearing Typical Application Areas
This bearing is ideally suited for high-performance machinery requiring high speed, high precision, and high rigidity. Key applications include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Robotics: High-accuracy joints and actuators.
- Medical Equipment: Dental handpieces and laboratory centrifuges.
