About Shaft Couplings

High-Speed Vibration-Damping Flexible Shaft Couplings
Use these gear-shaped couplings for high-speed and high-torque applications. A rubber center allows flexing so couplings can take on multiple types of misalignment while damping vibration and shock. With no metal-to-metal contact, there’s no need for lubrication. Fasten to your shafts by tightening the set screws, which bite into the shaft to hold it.
A complete coupling consists of two hubs and one center (each component sold separately).
Hubs have a keyway, except hubs for 1/4" and 3/8" shaft dia. do not have a keyway.

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.
