7017 ACEGA/P4A Bearing Product Overview & Core Advantages
The 7017 ACEGA/P4A is a single-row angular contact ball bearing engineered for applications demanding exceptional precision and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and rotational stability. Its 25° contact angle is optimized to support significant combined loads, efficiently handling both radial and one-directional axial forces. The Extra Light (A) preload minimizes deflection under load, ensuring high system rigidity and precise positioning, making it ideal for high-reliability, high-precision machinery.
7017 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| EGA | Universal Matchable bearing, supplied as one of a matched set of 2 bearings (SU arrangement) for optimized preload and performance. |
| P4A | High precision tolerance class, exceeding ABEC 7 standards, for applications requiring minimal runout and vibration. |
7017 ACEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The Extra Light preload (Class A) and P4A tolerance class work in concert to provide exceptional stiffness and rotational accuracy, critical for minimizing deflection in high-speed spindles.
- Superior Load Capacity: The 25° contact angle and robust chrome steel construction enable the bearing to handle high combined radial and axial loads effectively.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures stable operation and low centrifugal forces, contributing to the high limiting speed of 28,000 rpm. The open design facilitates efficient lubrication management.
- Universal Matching Capability: As part of a universally matchable (SU) set, these bearings can be mounted in tandem or back-to-back arrangements to achieve specific preload and stiffness characteristics without selective matching.
7017 ACEGA/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for demanding applications in:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Gearboxes: Where high rotational accuracy and rigidity are paramount.
- High-Frequency Motors and Spindles: Applications requiring minimal vibration at extreme speeds.
- Medical and Laboratory Equipment: Centrifuges and other high-speed precision instruments.
