S7017 ACD/P4A Bearing Product Overview & Core Advantages
The S7017 ACD/P4A is a high-precision, single-row angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to handle combined loads, accommodating significant axial loads in one direction alongside radial loads. Its phenolic cage, preload capability, and factory-applied lubrication contribute to superior high-speed performance and operational reliability in precision machinery.
S7017 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| ACD | 25° Contact Angle | Optimized for handling high axial loads and providing high rigidity. |
| P4A | P4 (ABEC-7) Tolerance Class | Ensures extremely tight dimensional and running accuracy for high-precision applications. |
S7017 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 loads, making it ideal for applications with high axial thrust requirements.
- Superior High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, allowing for a high limiting speed of 9,000 rpm. This is further enhanced by the optimized internal geometry and effective lubrication.
- Precision Engineering: Manufactured to P4 tolerance with tight bore, outside diameter, and width tolerances, this bearing guarantees minimal runout and vibration for exceptional rotational accuracy.
- Sealed and Lubricated for Life: As a sealed bearing pre-lubricated from the factory, it is protected from contamination and is designed for long service life with minimal maintenance in its specified temperature range.
S7017 ACD/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally suited for:
- Machine Tool Spindles
- High-Speed Industrial Pumps and Compressors
- Precision Grinding Spindles
- Robotic Arms and Precision Gearboxes
