S7017 CD/HCP4A Bearing Product Overview & Core Advantages
The S7017 CD/HCP4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Its defining characteristic is the 15° contact angle and ceramic ball construction, enabling superior performance under combined radial and axial loads. Manufactured to P4 (ABEC-7) tolerance and featuring a phenolic cage, this bearing delivers exceptional rotational accuracy, low heat generation, and extended service life in demanding operational environments.
S7017 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| S7017 | Standard Metric Series, 85mm Bore | Denotes the fundamental size and series of the bearing. |
| CD | High Contact Angle (15°) & Optimized Internal Design | Indicates a design optimized for high axial load capacity and rigidity. |
| HC | Hybrid Ceramic (Ceramic Balls, Steel Rings) | Utilizes ceramic balls for reduced weight, lower friction, and higher speed capability. |
| P4A | ABEC-7 / ISO P4 Tolerance Class | Specifies ultra-precision dimensional and running accuracy. |
S7017 CD/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls (Si3N4) significantly reduces centrifugal forces, lowers operating temperature, and enables a higher limiting speed of 12,000 rpm. This also provides inherent electrical insulation and superior resistance to wear.
- High Rigidity & Load Capacity: The 15° contact angle is specifically designed to handle significant axial loads in one direction while simultaneously supporting radial loads, making the bearing exceptionally rigid.
- Optimized High-Speed Performance: The lightweight phenolic resin cage ensures stability and low friction at high rotational speeds, complementing the benefits of the ceramic balls.
- Precision & Reliability: Manufactured to P4 tolerance, this bearing guarantees minimal runout and vibration, which is critical for applications requiring high positional accuracy and smooth operation.
- Sealed & Lubricated for Life: As a sealed and pre-lubricated unit, it is protected from contamination and is designed for maintenance-free operation within its specified temperature range.
S7017 CD/HCP4A Bearing Typical Application Areas
