7017 ACD/P4ADT Bearing Product Overview & Core Advantages
The 7017 ACD/P4ADT is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. As part of a duplex tandem (DT) arrangement, this bearing is preloaded and matched to deliver superior performance under combined loads. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed spindles and other precision machinery where high rigidity and minimal runout are critical. The phenolic cage and optimized 25° contact angle contribute to its outstanding high-speed capabilities.
7017 ACD/P4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design, 25° contact angle |
| P4A | High precision tolerance class with specific running accuracy requirements |
| DT | Duplex Tandem arrangement - two bearings mounted in tandem for increased axial load capacity |
7017 ACD/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem arrangement provides exceptional stiffness, enabling the bearing to handle significant combined loads (radial and axial) while maintaining precision. The preloaded configuration eliminates internal clearance, ensuring zero-play operation.
High-Speed Performance: Featuring a phenolic resin cage, this bearing achieves excellent high-speed capabilities with a limiting speed of 17,000 rpm. The lightweight cage material reduces centrifugal forces while maintaining dimensional stability at elevated temperatures.
Precision Engineering: Manufactured to P4A tolerance standards with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration for precision applications.
Optimized Design: With 21 precision balls of 14.288 mm diameter and a 25° contact angle, the bearing is engineered for optimal load distribution and high-speed operation.
