What is the main feature of the SFC model coupling?

The SFC model coupling features a lightweight, high-strength aluminum alloy clamp hub, offering a high torsional rigidity that enables high responsiveness. It is available in a high-rigidity single element type and a double element type with spacers for flexibility, both designed to reduce inertia by linking the hub outer diameter with the shaft diameter.

How does the SFC model ensure ultra-low inertia?

The SFC model achieves ultra-low inertia by adjusting the clamp hub's outer diameter to match the adopted bore size. For smaller bore sizes, the outer diameter is reduced to minimize inertia, making it ideal for high acceleration operations. There are three shape patterns based on the bore size combinations.

What makes the installation of the SFC model simple and reliable?

The SFC model uses a clamp method for shaft fastening, requiring only the tightening of one bolt on each side for installation. The clamp hub is resistant to vibration and shock, ensuring a secure connection with friction-based power transmission, eliminating backlash. Both sides of the coupling are aligned with a dedicated jig to ensure concentricity.

Can it be used in clean room?

Yes, the SFC model offers a simplified clean solution with clean washing and assembly (ISO Class 6) and clean packaging. To enhance anti-corrosion effects, surface treatment changes and bolt upgrades to stainless steel or electroless nickel plating are implemented.
