The shaft and hub can be easily and quickly coupled using a single pressure screw.This facilitates assembly of equipment that requires positioning in the rotation and axial directions. It is also effective in locations requiring repeated mounting and removal. The concentricity of the shaft and hub is 0.02 mm, so relatively precise positioning is possible as well.
