Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screws to secure.

Parallel couplings have short, intermittent cuts that make them more rigid and able to handle more torque and speed than spiral couplings, but they’re worse at correcting misalignment. Use them in high-torque applications, such as linear test systems and scientific instruments. They’re sometimes called slit couplings.

Aluminum couplings are lightweight with good corrosion resistance.
