Made of high quality hardened steel, the TOOTHED COUPLINGS supplied by ABS can be mounted horizontally, vertically, or as special solutions depending on the required needs. Their small dimensions and low weight with a low mass moment of inertia result in great versatility for use in multiple applications for heavy industry. As flexible shaft connections, they are suitable for positive torque transmission, ensuring compensation of axial, radial and angular shaft displacements. Their permanent lubrication in the crowned spline generates friction conditions that ensure low-wear operation and extend their service life.
