Helical Flexible Couplings

HELI-CAL Flexure, flexible couplings are machined from single piece, homogenous high-strength materials into helical (curved beam) configurations which eliminate elastomeric elements like rubber bushings, spiders, rubber discs and pads. Helical couplings compensate for shaft misalignment and work at high speed, transmitting high torque at a constant velocity. There is zero backlash. No maintenance is needed.
