Couplings work well with dynamic reciprocation
This coupling variant was designed for machining spindles, flying shears and other applications with shock loads that can't have any backlash. The couplings have conical sleeve hubs for keyless torque transmission in highly dynamic, reciprocating loads. They work well with high-speed applications with frequent load reversals or stops, with no backlash characteristics and a high clamping force and concentricity. They have a positive stop on the conical ring, which ensures clamp screws will tighten to the right torque during installation, but the ring can't be tightened more than needed, so they are much easier to remove from shafting. Sizes range from 10 Nm (89 lbs-inch) to 2150 Nm (19027 lbs-inch), and can take English or metric bores with 6- to 80-mm diameters.
