7017 ACB/P4A Bearing Product Overview & Core Advantages
The 7017 ACB/P4A is a single-row angular contact ball bearing designed for applications demanding exceptional precision and high-speed performance. As a P4 (ABEC-7) tolerance class bearing, it guarantees superior running accuracy and rotational stability. Its key advantage lies in its ability to accommodate high combined loads, specifically substantial axial loads in one direction, making it an ideal choice for high-rigidity spindles and precision machinery where uncompromising performance is critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7017 | Basic bearing series, indicating a metric, medium-duty angular contact design with an 85mm bore, 130mm OD, and 22mm width. |
| ACB | Signifies a 25° contact angle and a specific internal design optimized for high rigidity and high-speed operation. |
| P4A | Denotes a P4 tolerance class (equivalent to ABEC-7) with specific dimensional and running accuracy requirements for precision applications. |
7017 ACB/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 minimizes deflection under load, ensuring high running accuracy for spindles.
- Superior Load Capacity: The optimized internal geometry, including a 9.525 mm ball diameter and 28 balls, enables high radial dynamic load rating (5648 lbf) and static load rating (5040 lbf), effectively handling combined radial and axial loads.
- Optimized High-Speed Performance: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 18,000 rpm. The open seal type allows for efficient lubrication management in high-speed systems.
- Pre-Loaded for Immediate Performance: The bearing is supplied with a preload, which increases system stiffness, reduces vibration, and ensures precise rotational performance from the moment of installation.
7017 ACB/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is engineered for high-performance applications, including:
- 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: For applications demanding minimal runout at extreme speeds.
- Medical and Laboratory Equipment: Centrifuges and other precision rotary devices.
