torsionally rigid coupling / disc / for extruders / for printing machines

Protection with repetitive accuracy: the ARPEX torque limiters in the AKR and AKA series provide unequivocal disconnection and torque-free, complete separation of the coupled units (wear-free) at both slowly and quickly increasing torque. Due to the degressive characteristic of the plate springs, the system torque decreases immediately when the disconnecting process starts.
The ARPEX torque limiters ensure a very high degree of repetitive accuracy even after frequent disconnecting processes in which the geometry of the close-fitting splines always re-engages in the same position and ensures torque transmission with no play. They are equipped with freewheeling with deep-groove ball bearing (for-life lubrication) and are designed for a temperature range from −30°C to 80°C. Due to high material quality and production precision, the ARPEX torque limiters feature extremely low vibration, which protects the connected machine components.
