Selecting torque limiters and

couplings for high speed tasks

Drive axes in the high-speed range require reliable clutches and couplings, because
if collisions occur at high speeds, they can cause severe damage. But couplings do
not only provide overload protection. Dynamic and high-precision shaft misalignment
compensation couplings also create the prerequisites for exact measurement results.

The experts at Mayr guide us through product selection for these applications.
