S7002 ACD/P4A Bearing Product Overview & Core Advantages
The S7002 ACD/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This sealed bearing features a phenolic cage and comes pre-lubricated, offering reliable performance in high-speed operations. Its key advantage lies in its ability to accommodate combined radial and axial loads simultaneously, making it an ideal choice for compact, high-performance mechanical systems where space and precision are critical.
S7002 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| ACD | 25° Contact Angle, High Precision | Optimized for handling significant axial loads and providing high rigidity. |
| P4A | ABEC-7 / P4 Tolerance Class | Guarantees ultra-precise running accuracy and minimal vibration for high-speed applications. |
S7002 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction enable the bearing to support substantial combined radial and axial loads, ensuring stable operation under demanding conditions.
- Superior High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, while the pre-lubrication and sealed design contribute to a high limiting speed of 50,000 rpm, making it an excellent high-speed bearing.
- Precision Engineering: Manufactured to P4 (ABEC-7) tolerance, this bearing delivers exceptional running accuracy, low noise, and minimal heat generation, which is critical for spindle and other precision applications.
- Maintenance-Free Operation: The integral seals protect against contamination and retain lubricant, offering long service life without the need for re-lubrication within the specified temperature range of -30°C to 110°C.
