S7022 CD/HCP4A Bearing Product Overview & Core Advantages
The S7022 CD/HCP4A is a precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and high-speed performance. As a single, preloaded bearing, it is designed to support combined loads (simultaneous radial and axial loads) with high rigidity. Its construction with a phenolic cage and ceramic balls enables superior high-speed capabilities and reduced heat generation, making it ideal for high-reliability, high-precision machinery.
S7022 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7022 | Basic bearing designation, indicating a 110mm bore, 170mm OD, and 28mm width. |
| C | Specifies a 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| D | Indicates a high preload for maximum rigidity and precise shaft positioning. |
| HC | Signifies Hybrid Ceramic construction, featuring ceramic balls for reduced weight, lower friction, and higher speed limits. |
| P4 | Denotes a P4 (ABEC-7) tolerance class, ensuring ultra-precision and minimal runout for critical applications. |
S7022 CD/HCP4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The preloaded single arrangement eliminates internal clearance, providing exceptional system stiffness and accurate rotational performance, crucial for machine tool spindles.
- Superior High-Speed Performance: The combination of a lightweight phenolic resin cage and low-density ceramic balls significantly reduces centrifugal forces, enabling a high limiting speed of 9,500 rpm.
- Enhanced Durability and Life: Hybrid ceramic construction offers superior resistance to wear and operates effectively with minimal lubrication. The inherent properties of ceramic also provide electrical insulation and the ability to run at higher temperatures.
- Optimized Load Capacity: The 15° contact angle is engineered to handle significant combined loads, offering a robust solution for demanding applications.
S7022 CD/HCP4A Bearing Typical Application Areas
