MOR is the Oldham-type flexible coupling series perfect for integration into stepping motors, general-purpose motors and rotating shafts in general. The spacer's and hub's design (with setscrew, clamping, key and clamping + key fixing options) allows to reduce the overall foot-print while widening the bores selection as well as increasing the rated torque at the same time. The spacer, in hard polyacetal, affords a projection structure which enables larger lateral and angular misalignment to be effortlessly accepted since the projection acts as a support. Thus the bending moment does not arise and the allowable angular misalignment is increased up to 3° (instead of 1° - 1.5° in comparable models). MOR's torque reaches 160 Nm. In addition MOR is able to excellently absorb the vibrations since the amplitude under natural frequency is low. MOR is available in the range from 6 to 68 mm (0.236” to 2.677”) outer diameter and 1 to 38 mm (0.039” to 1.496”) bore diameter and is electrically insulated (up to 20 kV). It can be ordered with different bore diameters at hubs. The allowable operating temperature is between -20°C and +80°C (-4°F +176°F).

The MOM Oldham-type flexible coupling is distinguished by its spheroidal graphite cast iron (EN-GJS-400) metal spacer that connects the hubs. It yields an increased impact and fatigue resistance compared to resin spacers and allows to reach the highest torque (up to 352 Nm) and torsional rigidity (up to 46,000 Nm/rad) while providing optimal ductility properties at the same time. Furthermore it excellently compensates for large lateral (up to 1.4 mm / 0.055”) and angular misalignments (up to 2° instead of 1° - 1.5° in comparable models). So it is ideally suited for integration into general-purpose motors and rotating shafts with low speed and high torque characteristics in severe industrial applications. The spacer is self-lubricating for virtually maintenance-free enduring service. MOM flexible coupling is offered in a very wide selection of bore diameters ranging between 3 mm and 42 mm (0.118” to 1.653”), with setscrew, clamping, key and clamping + key type hubs. In addition it can be ordered with different bore diameters at hubs.
