FKXS 1635 spring coupling: new with stainless steel hubs

The FKXS 1635 spring coupling made of nickel-plated spring steel and stainless steel hubs is the medium spring coupling in our range. With a diameter of 16 mm and an overall length of 35 mm, it has medium performance values compared to other variants. In general, it has been developed for use in harsh environments: very vibration-damping with good compensation of misalignments with low restoring forces.

Compare our smaller variant FKXS 1225 and the larger FKXS 2650.
