The KTR-SI overload couplings are torque limiters available in various types of engagement (DK or SR, automatically engaging and FR load-separating, idle rotation) and designs (overload coupling with flange types or in combination with ROTEX jaw couplings).
Due to the wide variety of the overload couling the low-backlash and positive-locking ball engagement system provides solutions for almost every appplication.
The KTR-SI overload couplings are torque limiters available in various types of engagement (DK or SR, automatically engaging and FR load-separating, idle rotation) and designs (overload coupling with flange types or in combination with ROTEX jaw couplings).
The core of the overload couplings (safety couplings) is formed by the idle rotation elements. They uncouple the driving and driven side in case of overload while protecting the drive train from damages. After eliminating the overload, the rotation segments are manually re-engaged so that the drive is released again.
The KTR-SI FRA idle rotation and automatically re-engaging overload couplings are available as a flange type FT or in combination with the POLY-Norm flexible coupling (shaft-to-shaft connection). The low-backlash, positive-locking ball engagement system allows for optimum overload protection for torques up to 3,000 Nm.
