The KTR ROTEX GR 25 is a high-quality, torsionally flexible jaw coupling designed for reliable power transmission in various industrial machinery. This specific configuration, identified by GR25126215, features two hubs with bore diameters of 12.6 mm and 21.5 mm, allowing for the connection of shafts with differing sizes. Constructed from durable cast iron (EN-GJL-250) for the hubs and a resilient polyurethane spider, it effectively dampens shocks and vibrations, compensating for axial, radial, and angular misalignments. This ensures smooth operation, reduces wear on connected components, and extends the service life of the machinery. The ROTEX GR 25 is a proven solution for demanding industrial environments.
