    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.
