Double loop shaft coupling stainless steel V4A 1.4404 DKPSY2928

The shaft coupling DKPSY2928 made of V4A (1.4404) stainless steel is a double-loop coupling in a small design with clamping hubs with a diameter of 29 mm and an overall length of just 28 mm.

Its strengths include, firstly, its increased resistance to corrosion thanks to V4A stainless steel (1.4404) and, secondly, its thermal and electrical decoupling thanks to its double loops made of special polyurethane Hytrel® plastic.It has a medium torsional stiffness, low restoring forces and offers very high compensation of shaft misalignments, whether radial, angular or lateral. The DKPSY2928 is shock and vibration absorbing, has no moving parts, runs smoothly and is maintenance-free.
