76mm Diameter 2 Stage with Spacer Disc Coupling
Item number:
Description:
Thin pressed steel membranes act as the pivotal members in these couplings. Torque is resolved to simple tensile stresses in opposing segments of the membranes. These couplings have near-infinite life and a dynamically balanced construction which makes them suitable for applications requiring high rotational speed and high-level motion integrity e.g. machine tools, robots, centrifuges, turbines, dynamometers. This style is designed for greater radial misalignment and lower bearing loads.
