S71922 CD/HCP4A Bearing Product Overview & Core Advantages
The S71922 CD/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. As a single-row bearing, it is designed to accommodate high combined loads, primarily thrust loads in one direction, and offers superior high-speed capability. Its P4 (ABEC-7) tolerance class ensures minimal runout and vibration, making it ideal for high-rigidity, high-reliability systems. The combination of a ceramic ball material and a phenolic cage contributes to reduced weight, lower friction, and extended service life, especially in high-velocity environments.

S71922 CD/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and provides excellent electrical insulation, enabling superior high-speed performance and longer lubricant life.
Optimized Contact Angle & Preload: The 15° contact angle is optimized to handle high thrust loads efficiently. The bearing is supplied with a light preload, ensuring high system stiffness, precise rotational accuracy, and minimal axial play from installation.
Phenolic Resin Cage: The lightweight and robust phenolic cage offers excellent dimensional stability and low friction at high speeds, contributing to the bearing's high limiting speed of 10,000 rpm.
Precision & Sealing: Manufactured to P4 tolerance standards, this bearing guarantees smooth, quiet operation. It comes sealed and pre-lubricated, protecting against contamination and providing reliable, maintenance-free operation within its specified temperature range.
S71922 CD/HCP4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers, grinding spindles, and CNC lathes requiring high rigidity and precision.
- High-Frequency Motors & Spindles: Applications where reduced inertia and high rotational speeds are critical.
- Precision Instrumentation: Medical devices, optical scanners, and measuring equipment demanding minimal runout.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other high-performance rotational mechanisms.
