STE
Safety couplingsThe STE heavy-duty safety coupling from R+W Couplings features a keyway connection on both sides. An integrated claw coupling ensures the accommodation of alignment differences. The STE industrial coupling boasts an extremely robust design and highly precise overload protection. The coupling is torsionally rigid and features an integral heavy-duty bearing for support. This safety coupling is applied wherever torque overload occurs. 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.
