In addition to the Simple-Flex, WD, WDS, WDB, and WD-VA connecting shafts, Jakob also offers another standard series and customized solutions for bridging large center distances: the EKHZ series, based on EKH series elastomer couplings. The EKHZ series is primarily used in applications with medium operating speeds. It covers a torque range of 20 to 1600 Nm and allows maximum speeds of 3500 rpm with a minimum length of 50 cm. It is suitable for shaft diameters of 10 to 100 mm. The maximum achievable length of the EKHZ series is generally three meters. The EKHZ series allows for efficient vibration damping. The degree of vibration damping can be adjusted by adjusting the Shore hardness of the compensation elements. The plastic spiders used offer two advantages: even without a half-shell design, the couplings are pluggable, making them easy to install. Furthermore, the plastic provides thermal and electrical insulation. Due to the properties of the material used, these couplings can only be used up to 90°C, with the permissible transmission torque decreasing with increasing temperature.
