The RENK HYGUARD® safety coupling, type BW 140 (formerly STB 140), is a high-performance overload protection coupling designed to protect machines and systems from damage due to overload. It reliably disengages when a predefined torque is reached, effectively separating the drive train. This safety coupling combines robustness with precision and is designed for use in demanding industrial environments. Its construction allows for easy integration into existing systems and ensures a long service life with minimal maintenance. It is ideally suited for use in pumps, fans, compressors, and other rotating machinery where reliable torque limitation is essential. Protect your valuable equipment and minimize unplanned downtime by using the RENK HYGUARD® safety coupling.
