The Mayr ROBA®-DS Size 16 Type 9110.00010 Flexible Disc Coupling (Drawing No.: DS Y7110084 / Order Art No.: 7047440) is a high-precision, backlash-free steel disc coupling engineered by Mayr (Germany). Designed for demanding high-speed drive applications, it offers high torsional stiffness while compensating for axial, angular, and radial shaft misalignments.

The disc pack of the ROBA-DS series is constructed from high-tensile stainless spring steel, transmitting torque frictionally via robust clamping sleeves without mechanical wear, eliminating the need for lubrication or routine maintenance. This Size 16 Type 9110.00010 model delivers a nominal torque rating of 300 Nm and a peak overload capacity of 450 Nm. A key advantage of Art No. 7047440 is that the complete coupling assembly is dynamically balanced to ISO 1940 Grade G2.5 at 3000 rpm, minimizing vibration, reducing bearing loads, and ensuring smooth, ultra-precise high-speed performance.
