The Mayr ROBA®-ES Size 24 Type 940.022.A Flexible Elastomer Jaw Coupling (Order Art No.: 7000355) is a high-precision, backlash-free flexible coupling manufactured by Mayr (Germany). Designed specifically for servo drives and automated motion control applications, it ensures vibration-damped, electrically insulating, and backlash-free torque transmission between driving and driven shafts.

This ROBA-ES Size 24 model is equipped with two precision-machined hubs featuring Ø25 mm H7 bore diameters with standard DIN 6885 keyways for positive, slip-free torque transfer. At the core of the coupling is a high-grade red Polyurethane elastomer star element rated at 98 Shore-A (98Sh-A) hardness. This elastomeric insert delivers a optimal combination of torsional stiffness and vibration attenuation, supporting a nominal torque rating of 60 Nm and a maximum overload peak torque of 120 Nm while compensating for axial, angular, and radial shaft misalignments.
