THOMAS

The Thomas Disc Coupling transmits torque via packs of thin steel laminations bolted alternately to the hub and a spacer. The lamination packs are stiff in the direction of rotation but flex elastically and thus compensate angular and axial misalignment, and in the version with a spacer (two lamination packs) additionally radial (parallel) shaft misalignment. Because the misalignment is taken up purely by the elastic deflection of the metal laminations, the coupling works without wear parts and without lubrication.

All-metal disc couplings combine high torsional stiffness and backlash-free torque transmission with maintenance-free operation and long service life. They are insensitive to high temperatures and suit speed-accurate, torsionally rigid drives that require moderate, lubrication-free and wear-free misalignment compensation (angular and axial, and parallel with a spacer). The lubrication-free design significantly reduces maintenance effort.

REEL supplies the Rexnord Thomas Disc Coupling (Regal Rexnord) including lamination packs as spare parts and supports selection and replacement.
