The KTR-SI with ROTEX (by KTR) features a protective coupling with up to 8.200 Nm, a shaft-to-shaft connectivity capability, three different designs (synchronous, fail, safe, as well as ratchet), a compatibility with the torsionally flexible ROTEX coupling, and an axial plugging funcitonality. In addition, the KTR-SI is also equipped with the most advanced calculation and simulation applications. This is for pinpoint accuracy in measuring the actual precise dimensions of torque limiters.
