7202 CDGA/P4A Bearing Product Overview & Core Advantages
The 7202 CDGA/P4A is a precision single-row angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. Its primary advantage lies in its ability to accommodate combined radial and axial loads simultaneously. Manufactured to a P4A tolerance class with an Extra Light (Class A) preload, this bearing offers superior running accuracy, high rigidity, and smooth operation, making it ideal for high-precision and high-reliability machinery.
7202 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CD | Specifies a 15° contact angle, optimized for high-speed applications and moderate axial loads. |
| G | Indicates the bearing is Universal Matchable (SU), allowing it to be mounted in pairs (back-to-back, face-to-face, or tandem) to adjust rigidity and load capacity. |
| A | Denotes an Extra Light preload (Class A), which minimizes friction and heat generation, contributing to higher limiting speeds. |
| P4A | Signifies a high-precision tolerance class with very tight dimensional and running accuracy tolerances for superior performance. |
7202 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P4A tolerance class and phenolic resin cage ensure minimal vibration and high running accuracy, providing stable and rigid support for shafts.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently handle combined radial and one-directional axial loads, a key feature of angular contact ball bearings.
- Superior High-Speed Performance: The lightweight phenolic cage and extra light preload work in tandem to reduce centrifugal forces and friction, enabling a high limiting speed of 95,000 rpm.
- Universal Matching Capability: As a Universal Matchable (SU) bearing, the 7202 CDGA/P4A can be precisely paired with another identical bearing to create a matched set, allowing engineers to configure the optimal stiffness and load-carrying capacity for their application.
7202 CDGA/P4A Bearing Typical Application Areas
This high-precision bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Dental and Medical Handpieces
- High-Speed Automation and Robotics
