Vibration-Damping Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.
A complete coupling consists of two hubs, one tire, and two quick-disconnect bushings.
Quick-disconnect bushings are easy to install and remove. Tighten their cap screws to secure them to your shafts. For information on quick-disconnect bushing styles, see Quick-Disconnect (QD) Bushings.

High-Speed Vibration-Damping Flexible Shaft Couplings
 |  |
(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.

Flexible-Shaft Shear Couplings
 |
To protect power-transmission components from damage, these couplings will shear or tear in overtorque conditions (approximately 10-20 times the maximum rated torque) to sever connections between shafts. They have a flexible center that not only compensates for misalignment, but also dampens vibration and shock loads. Couplings have no metal-on-metal contact, reducing noise and eliminating the need for lubrication. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.

High-Misalignment Vibration-Damping Precision Flexible Shaft Couplings
 |
Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment. They allow zero backlash (no play) and will run smoothly and quietly. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.
316L Stainless Steel—316L stainless steel couplings offer excellent corrosion resistance.

Set Screw Vibration-Damping Precision Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) | Components of a Coupling Shown Assembled |
The included set screw holds the coupling in place. 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 Vibration-Damping Precision Flexible Shaft Couplings
 |  |
(Each Component Sold Separately) |
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.
