7200 CDGB/P4A Bearing Product Overview & Core Advantages
The 7200 CDGB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable bearing supplied in a light preload (Class B) set of two, it is engineered to accommodate combined loads while providing high-speed capability. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-performance spindles and precision machinery requiring reliable, long-term operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7200 C | Basic series designation with a 15° contact angle. |
| DGB | Indicates a Universal Matchable (SU) bearing supplied in a light preload (Class B) duplex set. The two bearings are ground to a specific offset for precise axial play control when mounted face-to-face (DF), back-to-back (DB), or tandem (DT). |
| P4A | Denotes a super-precision tolerance class with enhanced dimensional and running accuracy beyond standard ABEC 7 (P4) levels. |
7200 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and duplex mounting create a highly rigid bearing system capable of supporting significant combined radial and axial loads in both directions.
- Superior High-Speed Performance: The lightweight phenolic resin cage and optimized internal geometry contribute to low friction and heat generation, enabling a high limiting speed of 185,000 rpm.
- Exceptional Precision: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for applications requiring extreme rotational accuracy.
- Optimized for Matched Sets: As a universal matchable bearing, it provides design flexibility for preload and stiffness optimization in various mounting configurations (DF, DB, DT).
7200 CDGB/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Rotary Systems: CNC rotary tables, indexing heads, and robotic arms.
- High-Frequency Motors: Spindles for PCB drilling and dental handpieces.
- Medical and Laboratory Equipment: Centrifuges and precision instrumentation.
