Flexible Couplings, Sleeve-Type Couplings

Sleeve-type couplings have a simple three-piece design, consisting of two identical set screw-type splined hubs (acetal) with a mating polyethylene sleeve. These couplings accommodate angular offsets up to 7° and lateral offsets up to.015" (0.35 mm). The A 5R21 series is available with 1/8”, 3/16”, or 1/4” (4, 5, 6 mm) bores with an outside diameter of 37/64” (14.7 mm). The A 5R23 series is available with 5/16”, 3/8”, 7/16”, or 1/2” (8, 10, and 12 mm) bores with an outside diameter of 1-5/64” (27.4 mm). No lubrication is necessary for these couplings.
