Accessories, Flexible Couplings Shaft encoders must be protected against excessive mechanical stresses, which occur whenever there are angular, axial, or radial misalignments between the machine and shaft encoder shafts. Our flexible couplings can compensate for this within limits. Plastic coupling Set screw Absolute max. speed Torque max.
