S71900 CD/HCP4A Bearing Product Overview & Core Advantages
The S71900 CD/HCP4A is a single-row angular contact ball bearing engineered for ultra-high precision and high-speed applications. Featuring a compact design with a 10mm bore, this precision bearing is designed to handle combined loads, primarily thrust loads in one direction, while maintaining exceptional rotational accuracy. Its P4 (ABEC-7) tolerance class and ceramic ball construction deliver superior performance in demanding environments, making it an ideal solution for applications requiring minimal runout and high reliability.
S71900 CD/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S71900 CD/HCP4A reveals its specific technical configuration:
- S7: High-precision bearing series.
- 1900: Denotes the specific size series with a 10mm bore and 22mm outside diameter.
- C: Indicates a 15° contact angle, optimized for high-speed operation.
- D: Signifies a phenolic resin cage for reduced weight and superior high-speed performance.
- HC: Indicates the use of hybrid ceramic balls (silicon nitride).
- P4: Denotes the P4 (ABEC-7) tolerance class, ensuring ultra-precise dimensions and running accuracy.
- A: Indicates that the bearing is supplied with a specific preload for enhanced rigidity.
S71900 CD/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a lightweight phenolic cage (D) and low-friction ceramic balls (HC) significantly reduces centrifugal forces and heat generation, enabling a high limiting speed of 95,000 rpm.
- High Rigidity & Precision: The P4 super-precision tolerances and factory-set preload (A) provide exceptional shaft positioning accuracy and system stiffness, minimizing deflection under load.
- Extended Service Life: Hybrid ceramic construction offers superior resistance to wear and provides electrical insulation, reducing the risk of arcing damage. The standard lubrication is suitable for the specified temperature range (-30° to 110°C).
- Optimized Load Capacity: The 15° contact angle is ideally suited for applications with high thrust loads, offering a dynamic load rating of 565 lbf and a static load rating of 248 lbf.
S71900 CD/HCP4A Bearing Typical Application Areas
This bearing is specifically designed for the most demanding high-speed and high-precision machinery, including:
- High-Frequency Spindles for PCB drilling and precision machining
- Turbocharger shafts in automotive and aerospace systems
- High-speed dental handpieces
- Precision gyroscopes and instrumentation
- High-performance robotics and direct-drive motors
