Ondrives.US Corporation, formerly Rino Mechanical Membrane (Disc) Shaft Coupling

Ondrives.US’ durable membrane couplings, also known as disc couplings or wafer spring couplings, utilize spring steel membranes as their pivotal members. Torque is resolved to simple tensile stresses in opposing segments of the membranes. We offer spring disc couplings in three configurations: single stage, double stage, and double stage with spacer. Single stage membrane couplings (460, 462, 660, 662) offer the highest torsional rigidity. They are designed to be used in pairs or with floating shafts. Double stage disk couplings (464, 466, 664, 666) provide higher flexibility than single stage models, but provide slightly less torsional rigidity. Double stage disk couplings with spacers (468, 470, 668, 670) offer the highest axial compensation, with lower torsional rigidity than standard double stage models.
