7202 ACD/P4A Bearing Product Overview & Core Advantages
The 7202 ACD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial loads), it features a 25° contact angle optimized for handling significant axial loads in one direction. Manufactured to P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and precision machinery. The bearing is preloaded and comes pre-lubricated from the factory for immediate, reliable operation.

| 7202 | Basic bearing series designation, indicating a 15mm bore, 35mm OD, and 11mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies a high-load capacity internal design. |
| P4A | Indicates a P4 (ABEC-7) tolerance class with specific dimensional and running accuracy requirements. |
7202 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design, combined with P4 precision and factory-applied preload, provides exceptional system stiffness and minimizes deflection under load, crucial for maintaining accuracy in machining and positioning applications.
- Superior Load Capacity: The 25° contact angle and optimized internal geometry enable the bearing to support high combined radial and axial loads efficiently.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the precision-ground chrome steel components and effective lubrication contribute to a high limiting speed of 63,000 rpm.
- Durability and Reliability: Manufactured from high-grade chrome steel for both rings and balls, ensuring long service life and resistance to wear. The open design allows for customized lubrication regimes to suit specific operational environments.
7202 ACD/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications where speed, precision, and rigidity are paramount. Key sectors include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Robotics: Joint and arm articulation systems.
- High-Frequency Motors and Spindles: PCB drilling spindles, dental handpieces.
