R+W’s ST series safety couplings reduces downtime in the aftermath of a machine crash, thereby increasing the availability and production performance of the equipment. Designed for use in shredders, crushers, rolling mills, steel mills, conveyor equipment and extruders, the compact, robust design of the coupling makes maintenancefree operation possible throughout its service life. This safety coupling can limit torque up to values of 160,000Nm, with an available shaft diameter range of 40-290mm.
