Product description

Double loop couplings GN 2250 connect shafts and compensate for axial, radial and angular misalignment. The special design has a shock and vibration damping effect, insulates connected shafts thermally and electrically and ensures very smooth running.

The stainless steel AISI 316L version is particularly suitable for applications in highly corrosive environments and, due to the FDA compliant material of the double loops, also in food areas.
