SF6801 Bearing Structural Features & Performance Benefits
- Flanged Outer Ring: The integrated flange (OD: 23mm) ensures easy installation and precise axial positioning, enhancing mounting rigidity and stability.
- Stainless Steel Construction: Rings, cage, and shield made from stainless steel provide superior corrosion resistance, extending service life in harsh environments.
- High-Speed Capability: With a limiting speed of 27,000 rpm and a stainless steel cage, the bearing maintains stability and low wear at high rotational speeds.
- Precision & Load Capacity: Manufactured to ABEC-1 tolerance with a radial dynamic load rating of 388 lbf, it delivers consistent performance under radial loads.
- Versatile Lubrication: The open design allows for the application of specialized lubricants to optimize performance for specific temperature ranges (-30° to 110°C).
SF6801 Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical Devices: Used in surgical handpieces, dental tools, and diagnostic equipment requiring compact, corrosion-resistant components.
- Office Automation Equipment: Suitable for scanners, printers, and copiers where reliable, low-noise operation is critical.
- Instrumentation & Robotics: Applied in encoders, sensors, and small robotic joints due to its precise dimensions and high-speed capability.
