S71922 CE/HCP4A Bearing Product Overview & Core Advantages
The S71922 CE/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and reliability. This single-row bearing is distinguished by its P4 (ABEC-7) tolerance class and ceramic ball construction, enabling superior high-speed performance and extended service life. Its design is optimized to handle combined loads, accommodating significant radial loads alongside thrust loads in one direction. The inclusion of a phenolic cage and pre-applied lubrication further enhances its suitability for high-velocity and high-rigidity operational environments.
S71922 CE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates the use of Hybrid Ceramic balls (Silicon Nitride), which reduce friction, heat generation, and wear, contributing to higher limiting speeds and longer life. |
| HC | Denotes a High-Capacity design, optimized for increased load ratings. |
| P4A | Specifies the P4 (ABEC-7) tolerance class and a 15° contact angle, ensuring ultra-precise running accuracy and optimized axial load capacity. |
S71922 CE/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces and friction, enabling a high limiting speed of 14,000 rpm and providing excellent resistance to wear and heat.
- High Rigidity & Load Capacity: The 15° contact angle and optimized internal geometry provide robust support for combined radial and axial loads, with a dynamic load rating of 9068 lbf and a static load rating of 7762 lbf.
- Superior High-Speed Performance: The lightweight, self-lubricating phenolic resin cage ensures stable operation at high rotational speeds, minimizing vibration and cage wear.
- Sealed & Pre-Lubricated: The sealed design with factory-applied lubrication protects against contamination and provides long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
