Cam couplings ROBA-ES with elastomeric inserts with asterisks of different hardness (Shore) from the company Mayr designed for precise torque transmission, without backlash. They are able to compensate for axial, radial and angular deviations in the shaft connection, reduce the influence of the vibration factor. Very practical and simple articulation, suitable for blind assembly, does not require further maintenance. This type of couplings can be used in a wide range of ambient temperatures.
Modular construction design with a wide range of possible connecting elements. The following types of elastic sprockets are available for order, which generally determine the main characteristics of the coupling:
80 SH A (blue)
92 SH A (yellow)
98 SH A (red)
64 Sh D (green)
