CU

Features

・Clamp-style couplings,available in a wide range combination of diameters:φ4 to φ13.
・Hubs and disk are made of sintered iron alloy for low cost.
・Higher tolerances for parallel and angular misalignments,and vibration than metal-plate couplings.

・Polyimide plate-type is particularly strong against misalignment,with good heat resistance and high electrical insulation.
