7017 CD/P4A Bearing Product Overview & Core Advantages
The 7017 CD/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Designed to accommodate primarily axial loads in one direction combined with radial loads, this bearing features a 15° contact angle and P4 (ABEC-7) tolerance class for exceptional running accuracy. Its phenolic resin cage and factory-applied lubrication enable reliable high-speed operation up to 16,000 rpm, making it ideal for precision spindles and machine tools where rigidity and minimal vibration are critical.
Model Code Breakdown
| Suffix Code | Technical Meaning | Performance Significance |
|---|---|---|
| CD | Optimized contact angle and internal design for high rigidity | Provides stable axial load capacity and precise shaft positioning |
| P4A | P4 (ABEC-7) tolerance class with enhanced running accuracy specifications | Ensures ultra-precision performance with minimal runout and vibration |
7017 CD/P4A Bearing Structural Features & Performance Benefits
- High Precision Construction: Manufactured to P4 tolerance class with bore diameter tolerance of -0.008mm to 0 and outside diameter tolerance of -0.009mm to 0, ensuring exceptional dimensional stability and running accuracy
- Optimized Load Capacity: The 15° contact angle design provides superior axial load capacity in one direction while maintaining excellent radial load capability (15,210 lbf dynamic / 14,738 lbf static)
- High-Speed Performance: Phenolic resin cage reduces centrifugal forces and friction, enabling reliable operation at limiting speeds of 16,000 rpm
- Thermal Stability: Phenolic cage material maintains dimensional stability across the operating temperature range of -30° to 110°C
- Preload Capability: Designed to accommodate preload for enhanced system rigidity and reduced deflection under load
