What's the Performance Features of 7002AC P4A GA Bearing?
The 7002AC P4A GA bearing is a high-performance precision component with P4A-level ultra-high precision. Its angular contact structure with a 25° contact angle can efficiently handle large combined radial and axial loads. Made of high-quality materials, it significantly reduces vibration during high-speed operation, achieving smooth and low-noise performance. It boasts strong durability and a long service life, and can maintain high precision even under harsh working conditions. Thus, it is an ideal choice for machine tool spindles, automated production lines, aerospace components, medical equipment and other fields that have extremely high requirements for accuracy and reliability.
What's the Applications of the 7002AC P4A GA Bearing?
The 7002AC P4A GA is a high-precision angular contact ball bearing, designed for high-speed, heavy-load scenarios requiring exceptional accuracy. Its P4A-grade precision, 25° contact angle, and durable brass cage make it a top choice across critical industries:
- CNC Spindles: Ensures micron-level precision in cutting/grinding, withstanding speeds up to 75,000 RPM (grease lubrication) while minimizing vibration.
- High-Speed Drilling Systems: Maintains tight tolerances under dynamic loads, reducing tool wear.
- Robotic Joints: Supports repetitive start-stop motions with ±0.01mm positioning accuracy, ideal for assembly line pick-and-place tasks.
- Precision Conveyors: Powers high-speed drives in electronics/medical production, reducing noise and extending service life.
- Aerospace Components: Performs in extreme conditions (e.g., satellite attitude controls, small aircraft actuators).
- Medical Devices: Enables low-vibration operation in high-speed centrifuges (up to 115,000 RPM with oil lubrication) and surgical robots.
- Laser Systems: Prevents optical path deviation in cutting/measuring equipment.
- EV Motors: Handles high speeds and thermal stress in powertrains, boosting efficiency.
Trusted for reliability in mission-critical operations, the 7002AC P4A GA bearing delivers precision where it matters most.
