7017 ACE/P4A Bearing Product Overview & Core Advantages
The 7017 ACE/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This bearing is designed to primarily accommodate combined loads (simultaneous radial and axial loads) in one direction. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for machine tool spindles and other high-performance machinery where minimal runout and vibration are critical. The phenolic cage and optimized internal geometry contribute to its suitability for high-speed operation.
7017 ACE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7017 | Basic bearing series designation, indicating a metric, single-row angular contact design with an 85mm bore, 130mm OD, and 22mm width. |
| ACE | Internal design suffix. Typically indicates a 25° contact angle and specific internal geometry optimized for high speed and rigidity. |
| P4A | Tolerance class suffix. Denotes a P4 (ABEC-7) precision grade, ensuring extremely tight dimensional and running accuracy tolerances. |
7017 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance class with a 25° contact angle, this bearing provides excellent dimensional stability and resistance to deflection under load, which is crucial for maintaining precision in machining and positioning applications.
- Superior Load Capacity: The optimized raceway geometry and use of 26 high-quality chrome steel balls enable the bearing to handle significant combined radial and axial loads efficiently.
- High-Speed Capability: The lightweight phenolic resin cage offers superior strength and guidance at high speeds, contributing to a limiting speed of 20,000 rpm. This cage material also provides good slip and emergency running properties.
- Optimized for Performance: The bearing comes pre-lubricated for immediate use. The open design allows for customized lubrication regimes to further enhance performance and service life in specific operating conditions.
