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.
