Connecting couplings Roba-DS (steel) productions Mayr designed for precise transmission of torque without backlash, they have maximum rigidity in relation to torsional forces and are immune to variable loads within the established limits of force values. Their robust and high-strength construction makes them the optimal choice for working in harsh production conditions, additional accessories and options extend the temperature range to extreme values (up to 250 °C).
A huge range of seventeen standard sizes presented in several types of configurations: single-hinged, double-hinged in combination with plates or with sleeves (7 different types). A wide range of clamping element variations are available: keyed bushings, with clamping rings, clamping bushings, split bushings, flanges, etc..
