Description

The SigmaDrive SD100 coupling is able to resist propeller thrust when installed as a standalone coupling directly from the shaft to the output flange on the engine’s transmission. The SD100 SigmaDrive couplings is able to absorb 73.6 ft-lbs (100 Nm) of torque for shaft sizes between 1 1/2″ ~ 1 3/4″ in diameter (30mm ~ 45mm). 

The SigmaDrive reduces and even eliminates vibrations that originate from an imperfect alignment between the propeller shaft and the engine, compensating for up to 3 degrees in all directions thereby guaranteeing a longer trouble-free life for all the associated components.

The coupling is manufactured from a special bronze alloy that makes it a premium product that is maintenance free. The internal component is hard-wearing with a long service life. No rubber is used in the construction of the SigmaDrive and its unique design compensates for the movement of the engine when under load form the propeller shaft.
