7017 ACD/HCP4ADGB Bearing Product Overview & Core Advantages
The 7017 ACD/HCP4ADGB is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This universally matchable (SU) bearing is designed to accommodate combined loads—simultaneously handling significant radial and axial forces. Its P4A tolerance class ensures ultra-precision operation, while the ceramic balls and phenolic cage contribute to superior high-speed capability and reduced weight. Pre-lubricated and featuring a light preload (Class B), it delivers immediate, reliable performance with high rigidity and extended service life in precision machinery.
7017 ACD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle, optimized for high axial load capacity. |
| HC | Hybrid Ceramic: Features ceramic balls for reduced friction, higher speed, and longer life. |
| P4A | Ultra-Precision Tolerance Class: Provides extremely tight dimensional and running accuracy. |
| DGB | Universal Matchable (SU): Indicates the bearing is ground for universal matching in pairs or sets for preload control. |
7017 ACD/HCP4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design with a 25° contact angle and dual-bearing matched set configuration provides high rigidity, enabling stable operation under significant combined radial and axial loads.
- Superior High-Speed Performance: The combination of ceramic balls (reducing centrifugal forces and friction) and a lightweight phenolic resin cage allows for a high limiting speed of 28,000 rpm, making it an ideal high-speed bearing.
- Precision and Longevity: Manufactured to P4A tolerance for exceptional running accuracy. The open design, when used in a properly sealed housing, combined with pre-lubrication, ensures consistent performance and reduced maintenance needs.
- Universal Matchability: As a Universal Matchable (SU) bearing, it can be paired in any combination to achieve the desired preload and stiffness without selective matching, simplifying installation and inventory.
