The maximum allowable rotation speed is 59,000 rpm, the highest specification coupling!

The KTR Group exhibited at SPS (Smart Production Solutions) held in Nuremberg, Germany from November 26 to 28, 2019. We showcased torque measuring devices and couplings (leaf spring type, jaw type), and many people from around the world visited our booth.

We have numerous achievements in Japan, particularly in the positioning devices of the machinery industry. ☆Three Key Points to Note about ROTEX GS Compact☆ 【1】Overwhelming reduction in axial dimensions! Depending on the frame number, the axial dimension is reduced by approximately 30% (compared to our standard products). It is ideal for compacting positioning devices and servo-driven devices. Example) Size 24 standard ROTEX GS total length 78mm vs. GS compact total length 54mm 【2】Increase in allowable rotational speed For size 24 (rated torque 60Nm) and above, an axial slot hub is adopted. While there is a disadvantage of needing to tighten bolts in two places, it has good balance in the direction of rotation and is suitable for high-speed rotation. 【3】Allowable torque and allowable eccentricity remain unchanged! Since the contact area with the shaft is reduced, some consideration for slip torque is necessary when not providing a keyway, but the core specifications of the coupling, namely allowable torque and allowable eccentricity, remain unchanged.

This time, we are introducing the ROTEX GS compact. The servo coupling ROTEX GS is well-loved by many companies not only in Europe but also in the Japanese market. To cater to customers who want to save space, KTR has released the ROTEX GS compact!! For example, the axial length of GS 24 compared to GS 24 compact is reduced by an impressive 30%☆ This product is well-received in the machine tool industry and applications such as ball screws for positioning devices.
