ST2
Safety couplingsThe ST2 heavy-duty safety coupling from R+W Couplings is a version with an integral elastomeric connection. This industrial coupling is used for direct drive and in applications where torque overload occurs. The ST2 safety coupling features a highly robust, simple design, and offers very precise overload protection. This industrial coupling from R+W is equipped with one type of elastomeric element. This dampens vibrations and can accommodate both lateral, axial, and angular misalignments. The maximum torque of the industrial coupling can also be manually adjusted using an adjusting wrench. This wrench can be ordered separately. For specific inquiries about safety couplings or other industrial couplings, please contact VARIODRIVE.
