CHP Model

This coupling features a highly elastic resin boot (polyester resin) that effectively absorbs vibrations and minimizes shaft reaction forces caused by installation misalignment. Its integrated design, which combines an aluminum alloy hub and boot into a single unit, makes it compact and lightweight. Thanks to this integrated structure, installation and removal are easy, and there is no backlash.
