SK1
Torque limitersThe SK1 safety coupling from R+W Couplings features a simple and compact design. This design enables fast and accurate disengagement detection and disengagement. In the disengaged state, this precision coupling has very low friction. Due to the friction clamp connection, this safety coupling is completely free of play. The integral bearing makes it easy to mount a toothed belt pulley or gear. The maximum torque of the SK1 coupling can also be manually adjusted using an adjusting wrench. This key can be ordered separately. For specific inquiries about safety couplings or other precision couplings, please contact VARIODRIVE.
