S71922 CE/P4A Bearing Product Overview & Core Advantages
The S71922 CE/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This P4 (ABEC-7) tolerance class bearing is preloaded and pre-lubricated, making it ideal for machine tool spindles and other high-speed machinery where superior running accuracy and minimal deflection under load are critical. Its design is optimized to handle significant combined loads (radial and axial) simultaneously, providing a compact and reliable solution for demanding operational environments.
S71922 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S | Designates a super-precision bearing series. |
| 7 | Indicates an angular contact ball bearing design. |
| 1922 | Specifies the bore diameter (110 mm) and series size. |
| CE | Denotes a 15° contact angle and specific internal design optimizations for high-speed operation. |
| P4A | Signifies the P4 (ABEC-7) tolerance class and that the bearing is supplied with a preload. |
S71922 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Running Accuracy: The single-row angular contact design, combined with a 15° contact angle and P4 precision, ensures extremely low runout and high system stiffness, which is vital for applications like machining centers.
- Superior Load Capacity: Engineered to support combined radial and axial loads effectively. With a dynamic load rating of 9068 lbf and a static load rating of 7762 lbf, it offers reliable performance under significant stress.
- Optimized High-Speed Performance: The lightweight phenolic resin cage minimizes centrifugal forces, contributing to a high limiting speed of 12,000 rpm. The standard lubrication is formulated for stable operation within this range.
- Precision and Durability: Manufactured from chrome steel for both rings and balls, this bearing ensures long-term dimensional stability and wear resistance. The tight dimensional tolerances guarantee consistent performance.
S71922 CE/P4A Bearing Typical Application Areas
