With this brandnew developed cuppling flattening the motor shaft and using grub screws is obsolete
Due to the symmetric buildup there is no imbalance.
The extremely small slit cares for a nearly complete surrounding of the motor shaft (spring steel/titan shaft). This caters for a loss-free transfer of the torque onto the cuppling ? at absolute concentricity
Adoption is also possible with motor shaft that is already flattened.
Made in Germany
For 5mm Motor Shaft
Flex axle 5mm
Measures: diameter 18,5mm, length 40mm
The degree of the flattened surface must not exceed 15% (0,6 mm) of the shaft diameter
