7202 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7202 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. As a universal matchable (SU) bearing supplied in a pre-matched duplex set, it delivers superior rigidity and can accommodate combined radial and axial loads simultaneously. Manufactured to the stringent P4A tolerance class and featuring an Extra Light (A) preload, this bearing is engineered for high-precision, high-reliability machinery where minimal runout and stable operation are critical.
7202 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7202 | Basic bearing series and size designation (15mm bore, 35mm OD). |
| C | 15° contact angle. |
| D | The bearing is part of a duplex pair (two bearings). |
| P4A | High precision tolerance class (superior to ABEC 7). |
| DGA | Universal Matchable arrangement (SU). When mounted in a specific configuration (face-to-face, back-to-back, or tandem), the set achieves a pre-defined preload. |
7202 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex set configuration provides significantly increased system rigidity, enabling the bearing to handle substantial combined loads (radial and axial) with high stability.
- Superior Precision & Speed: Manufactured to P4A dimensional and running accuracy standards, this bearing ensures minimal vibration and noise. The phenolic cage and optimized internal geometry contribute to a high limiting speed of 95,000 rpm, making it an ideal high-speed bearing.
- Optimized Preload: The Extra Light (A) preload eliminates internal clearance, resulting in greater shaft positioning accuracy and enhanced stiffness for the final application without generating excessive heat.
- Premium Materials: Constructed from chrome steel for both rings and balls, ensuring high durability and long service life under demanding operating conditions.
7202 CD/P4ADGA Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Dental and Medical Handpieces
- Aerospace Control Systems
