torsionally rigid coupling / disc / high-torque / sleeve
torsionally rigid, disc
Max.: 10,000 rpm (62,831.85 rad.min-1)
Min.: 2,400 rpm (15,079.64 rad.min-1)
This item is especially known for the zero backslash design, but there are other important factors to be taken into account, such as the highest torsional stiffness.
Note that all components of this model are made of metal (the discs are constructed of stainless steel and the hubs of aluminum), while low inertia and moderate-high torque are also guaranteed by the manufacturer.
