About Shaft Couplings

Clamping Vibration-Damping Precision Flexible Shaft Couplings


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. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).
A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.

Clamping Flexible Shaft Couplings


Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screw to secure. Also known as Lovejoy® couplings, they have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are aluminum for light weight and good corrosion resistance.
Hytrel spiders provide fair vibration damping and excellent chemical resistance. Polyurethane spiders provide fair vibration damping and good chemical resistance.
