The SK1 safety coupling from R+W Couplings has a simple and compact design. This design provides fast and accurate disconnection detection and disconnection. When disengaged, this precision coupling has very low friction. Due to the friction clamp connection, this safety coupling is absolutely free of play. The integral bearing makes it easy to fit a timing belt pulley or sprocket. The maximum torque of the SK1 coupling can also be adjusted manually with an adjustment key. This key can be ordered separately. For specific questions about safety coupling or other precision couplings, please contact VARIODRIVE.
