Helical Couplings

Helical couplings are designed to compensate for shaft misalignment while transmitting high torque at a constant velocity and with zero backlash. Helical couplings are ideal for handling parallel, axial (± 0.25” max.), and angular misalignment (5° max.).

They are a single-piece construction with long spiral cuts in the 7075-T6 aluminum body. These couplings have high fatigue resistance, they can adapt to high- and low-speed applications, and they do not require lubrication. They are recommended for use in drive systems and motion control systems connecting servomotors (or conventional motors) to a shaft, ball screw, or lead screw. They can be found in CNC machines, wind turbines, air cooling units, aerospace instrumentation, and pumps. Bore diameter combinations are available on special order.
