S7000 CE/P4A Bearing Product Overview & Core Advantages
The S7000 CE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for handling combined loads where high axial and radial stiffness are critical. Manufactured to P4 (ABEC-7) tolerance class, it ensures superior running accuracy and is pre-lubricated for immediate use in high-speed applications up to 90,000 rpm.
S7000 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a high-precision bearing with specific internal design optimizations for superior performance. |
| P4A | Denotes the tolerance class P4 (ABEC-7) and that the bearing is supplied with a preload for immediate high-rigidity operation. |
S7000 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The combination of a 15° contact angle and an applied preload significantly increases system rigidity, minimizing deflection under load and ensuring precise shaft positioning. The P4 tolerance class guarantees exceptional dimensional and running accuracy.
- Optimized for High-Speed Operation: The lightweight phenolic resin cage minimizes centrifugal forces, reduces friction, and contributes to the high limiting speed of 90,000 rpm. This makes it an excellent high-speed bearing solution.
- Superior Load Capacity: The angular contact design efficiently supports combined radial and axial loads simultaneously. With a dynamic load rating of 680 lbf, it offers reliable performance in demanding applications.
- Ready-to-Install and Sealed: The bearing is sealed to protect against contamination and is pre-lubricated, ensuring long service life and reducing maintenance requirements.
