German McGill coupling McGill model McGill price

McGill couplings transmit motion by welding or bonding a thin-walled corrugated tube (bellows) directly to the two coupling halves. This coupling features a simple structure, compact dimensions, easy machining and installation, and high transmission accuracy. It is mainly used in low-power precision machinery and control mechanisms that require compact structures and high transmission accuracy. The coupling consists of two hubs and a thin-walled metal tube, connected by welding or bonding. Although many other materials are available, stainless steel and nickel are the most common materials for the metal tube. Nickel tubes are produced by electrodeposition.
