S7009 ACD/P4A Bearing Product Overview & Core Advantages
The S7009 ACD/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered to simultaneously handle combined radial and axial loads in one direction, this bearing features a phenolic cage and comes pre-lubricated for immediate service. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it an ideal choice for high-speed spindles and other precision machinery where reliability and performance are critical.
S7009 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| ACD | Angular Contact, 25° Contact Angle | Optimized for handling significant axial loads in one direction while supporting radial loads. |
| P4A | P4 (ABEC-7) Tolerance Class | Guarantees extremely tight dimensional and running accuracy for high-speed, low-vibration operation. |
S7009 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction provide high rigidity, enabling the bearing to effectively support combined loads with a dynamic load rating of 6210 lbf and a static load rating of 4860 lbf.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 17,000 rpm. This makes it a true high-speed bearing.
- Precision Engineering: Manufactured to P4 tolerance class, this bearing ensures minimal runout and vibration, which is critical for maintaining precision in machining and positioning applications.
- Sealed and Lubricated for Life: The sealed design protects against contamination, and the factory-applied lubrication ensures consistent performance within the specified temperature range of -30°C to 110°C, offering a long, maintenance-free service life.
S7009 ACD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes: Where high rotational accuracy and rigidity are required.
- High-Frequency Motors and Spindles: Applications demanding low vibration and high-speed capability.
- Medical and Laboratory Equipment: Centrifuges and other precision instruments.
- Robotics and Automation: Precision joints and drive systems.
