Torque limiter for gearboxes
Up to 2,800 Nm of torque and 65 mm bore diameters.
A safety coupling designed to be mounted between the motor and gearbox using a B5 spacer flange. Available in sliding (DF) and disengage (DSS/F/SG-PR-V) versions. Placing the limiter on the high-speed side (between the motor and gearbox) allows for a significantly smaller device size and reduced costs compared to output-side solutions.
