Shaft and hub can be easily and quickly coupled by tightening a clamping bolt located on the flange surface.Fastening is accomplished using fewer bolts than with mechanical systems, and there is no slotting as with mechanical systems, so high-precision coupling with a concentricity of 0.05 mm is possible.

**Many variations**

Steel construction is standard, but there are many variations, including simple anti-rust specifications, stainless steel specifications, and short specifications.
