With the Lightweight safety couplings of the SL series R + W can save up to 60% weight compared to standard models. This was achieved through the use of novel materials and surface treatments as well as constructive optimizations.
The model SL2 from this model series is a safety coupling for direct drives. The coupling provides torsionally stiff shaft offset compensation through the built-in stainless steel metal bellows and the very rigid safety part. The low weight and the low moment of inertia of this coupling together with the high rigidity make it possible to use it even with large dynamics. The inertia in the entire drive train can be reduced. This increases the component life. The SL2 reliably limits torques from 10 to 400 Nm for shaft diameters up to 60 mm.
