Additional Information

TORQTUBE Couplings are simple assemblies consisting of two aluminum split-clamp hubs, and a rigid Delrin torque tube. An internal compression and radial play.

The dovetail shaped dogs on the inside faces of the hubs snap into mating recesses in the torque tube to transmit power, and to hold the coupling together as an integral assembly.

Both models can handle up to .025" of parallel I \ misalignment and up to 5º of angular misalignment.

The couplings clamp to round shafts. No set screws of shaft flats are required.
