Disengaging SIKUMAT® SR … with single rollers Advantages • Disengages in case of overload – separation of input and output • Integral fixed bearing • Keyway in connecting flange for maximum torque capacity • Calibrated micro adjustment of torque setting possible, even post-installation • Cost effective The Single Roller Principle The torque is transmitted via rollers which are pressed into detents by Belleville springs. When the preset limit torque has been reached, the detent ring moves axially and the SIKUMAT® disengages. A locking mechanism holds the detent ring while it is in disengaged mode. FF FF Function • When the preset limit torque has been reached the SIKUMAT® disengages the input and output. Switching ring • After the overload has been eliminated the SIKUMAT® can be switched on again manually. • This means that an axial switching force must be applied to the switching ring.
