About Shaft Couplings

Set Screw Flexible Shaft Couplings
Each hub includes a set screw (unless noted), which bites into your shaft to hold the coupling in place. Also known as Lovejoy® couplings, these three-piece couplings have a spider-shaped cushion between two hubs to reduce shock and handle minor shaft misalignment.
Buna-N spiders provide good vibration damping and chemical resistance. Hytrel spiders provide fair vibration damping and excellent chemical resistance. Polyurethane spiders and split spiders provide fair vibration damping and good chemical resistance.

Two-Piece Shaft Coupling Bridges
When your shafts are not close enough to use standard couplings, these have the length to bridge the gap. Install them anywhere on a shaft without removing components or having access to the ends of the shaft. Tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.
