Diaphragm Disc Couplings

Diaphragm Couplings produced by REACH are designed for applications requiring high torque transmission and high precision. Its diaphragm is made of stainless spring steel, which has high strength, good torsional rigidity, strong ability to compensate deviation, low restoring force, corrosion resistance and high temperature resistance. The flexibility of this coupling allows it to accommodate axial, radial and angular misalignments. It is also maintenance-free, making it an excellent choice for applications that require minimal downtime.
