7017 ACDGB/HCP4A Bearing Product Overview & Core Advantages
The 7017 ACDGB/HCP4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining characteristic is the 25° contact angle and Universal Matchable (SU) designation, allowing bearings to be mounted in sets (typically 4) to achieve optimal stiffness and handle combined loads (radial and axial). Manufactured to the stringent P4A tolerance class, it features a phenolic cage and ceramic balls, contributing to its low weight, high-speed capability, and extended service life. This bearing is pre-lubricated and designed for applications demanding exceptional rotational accuracy and reliability.

| Suffix Code | Technical Meaning |
|---|---|
| ACD | Designates a 25° contact angle, optimized for high axial load capacity. |
| GB | Indicates a specific internal design and clearance for Universal Matchable (SU) bearings. |
| HC | Signifies the use of Hybrid Ceramic balls (Silicon Nitride). |
| P4A | Denotes an ultra-precision tolerance class with enhanced running accuracy. |
7017 ACDGB/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Performance & Rigidity: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 17,000 rpm. The 25° contact angle provides excellent rigidity under axial loads.
- Superior Load Capacity: Engineered to handle significant combined radial and axial loads simultaneously. The universal matching (SU) feature allows for preloading in sets, further enhancing system stiffness and load distribution.
- Precision & Longevity: Manufactured to P4A tolerance standards for minimal runout and vibration. Ceramic balls offer superior wear resistance, lower friction, and extended service life compared to standard steel balls.
- Thermal Stability: The phenolic cage and ceramic components provide stable performance across the specified temperature range (-30°C to 110°C).
