Description

Miniature Bellows Coupling series MK are are most suited for feedback devices, small motors, including stepping and servo motors.

Torque levels range from 0.05 – 10 Nm depending on the model. Shaft sizes possible range from 1-28mm. The MK series couplings are maintenance-free and have an infinite service life, if the tolerances are not exceeded. The bellows are made of flexible, high-grade stainless steel. The hubs are made from aluminium. MK4 series with radial set (grub) screws and press fit connection from 0.5-10Nm.

The couplings provide completely backlash free power transfer.
