ST

Safety couplings

The ST heavy-duty safety element from R+W Couplings serves as the foundation for all ST safety couplings. It features a robust design and provides highly precise overload protection. The element is adjustable in the field and this setting can be easily read. The temperature range is from -30 to +120 degrees Celsius. The element is treated to resist corrosion. 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 get in touch with VARIODRIVE.
