One-Piece Flexible Couplings

Flexures are power transmissions made from single, high-strength material.

They performs with greater misalignment and higher speed, transmitting high-torque, constant-velocity. Backlash is eliminated because there are no moving parts and no lubrication, and the couplings are corrosion-and-maintenance-free. Flexible couplings have a capacity from a fractional-to-950-HP at 3,600-RPM, and shaft-size from 2-to-40-mm.
