Clamping High-Parallel-Misalignment Flexible Shaft Couplings
Components of a Coupling Shown Assembled
(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. Also known as Oldham couplings, they have a slotted disc that allows hubs to slide independently—good for applications with parallel shaft misalignment. They also allow zero backlash (no play) and never need lubrication.
A complete coupling consists of two hubs and one disc (each component sold separately).
Aluminum hubs are lightweight and have good corrosion resistance. Stainless steel hubs offer excellent corrosion resistance.
Acetal discs stand up to high twisting forces. Nylon discs have excellent vibration and shock absorption. PEEK discs have excellent impact resistance and the chemical resistance to withstand a variety of acids and other harsh substances.

Cleaned and Bagged Flexible Shaft Couplings
Often used in electronics manufacturing facilities and other extra-clean environments, these shaft couplings are cleaned and individually bagged to keep out contaminants. Their plastic center also doesn’t outgas much, helping keep contaminants low as well. All are compatible with most commercial acids except concentrated nitric and sulfuric acid. Also known as Oldham couplings, their slotted center lets the hubs slide independently, so they’re good for applications with parallel shaft misalignment. They have zero backlash (no play) and never require lubrication.
