SK5
Torque limitersThe SK5 safety coupling from R+W Couplings for direct drive applications is equipped with clamp hubs and tapered press fit segments. In addition, this maintenance-free precision coupling has fast and accurate disengagement detection and disengagement. Due to the friction clamp connection, this coupling is absolutely free of play. The design ensures that this safety coupling can be easily assembled and disassembled, and provides both electrical and thermal insulation. The maximum torque can also be manually adjusted with an adjusting key on the SK5 coupling. This key can be ordered separately. Thanks to the forced bellows shape, the element can simultaneously compensate for lateral, axial, and angular misalignments. For specific questions about safety couplings or other precision couplings, please contact VARIODRIVE.
