High-Speed Vibration-Damping Flexible Shaft Couplings
Components of a Coupling Shown Assembled
(Each Component Sold Separately)
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.
