7017 ACD/P4A Bearing Product Overview & Core Advantages
The 7017 ACD/P4A is a single-row angular contact ball bearing designed for applications requiring exceptional precision and rigidity. Engineered to accommodate combined loads, it efficiently handles significant radial loads and unidirectional axial loads. A key feature is its P4 (ABEC-7) tolerance class, ensuring ultra-precise running accuracy for high-performance machinery. The phenolic cage and optimized 25° contact angle contribute to its suitability for high-speed operation and stable performance under demanding conditions.
Model Code Breakdown
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Designates a 25° contact angle and specific internal geometry optimized for high rigidity and precise axial positioning. |
| P4A | Indicates the bearing conforms to P4 tolerance class (equivalent to ABEC-7), with enhanced running accuracy and dimensional stability. The "A" suffix may denote specific tolerance deviations or special requirements within the P4 class. |
7017 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The 25° contact angle and P4 precision grade provide superior axial rigidity and running accuracy, essential for applications with minimal deflection requirements.
- Optimized Load Capacity: The design is engineered to support substantial combined radial and axial loads in one direction, making it ideal for preloaded arrangements.
- High-Speed Capability: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing to the bearing's limiting speed of 14,000 rpm.
- Pre-Lubricated & Ready-to-Use: The bearing is supplied lubricated, ensuring immediate operation and protection during the initial run-in period.
