S71910 CE/P4A Bearing Product Overview & Core Advantages
The S71910 CE/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This sealed bearing features a phenolic cage and is pre-lubricated, making it an ideal single-row bearing solution for systems subjected to combined radial and axial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, while the optimized design contributes to high-speed capability and long-term operational reliability in compact installations.
S71910 CE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| CE | Enhanced internal design with optimized contact conditions and stabilized internal clearance. | Provides lower noise and vibration levels, contributing to smoother operation at high speeds. |
| P4A | Indicates a tolerance class of P4 (ABEC-7) with specific dimensional and running accuracy requirements. | Guarantees exceptional dimensional precision and rotational accuracy for high-precision machinery. |
S71910 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 15° contact angle and precision-ground raceways enable the bearing to efficiently support significant combined loads (radial and axial), providing stable and rigid support for shafts.
- High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction, allowing for a high limiting speed of 26,000 rpm. This makes it suitable for high-speed spindles and other rapid-rotation applications.
- Sealed and Pre-Lubricated Design: The integral seals protect against contamination and retain lubricant, offering a maintenance-free solution that ensures consistent performance and a long service life within the specified temperature range of -30°C to 110°C.
- Precision Engineering: Manufactured to P4 tolerance with a bore diameter of 50 mm and a narrow width of 12 mm, this bearing is designed for compact, high-accuracy assemblies where space is at a premium.
S71910 CE/P4A Bearing Typical Application Areas
This precision bearing is ideally suited for applications requiring high speed, accuracy, and reliability, including:
- Machine Tool Spindles
- High-Frequency Motors
