German KWD coupling KWD model KWD price

KWD couplings transmit motion by welding or bonding a thin-walled corrugated tube (bellows) directly to the two half-couplings. This type of coupling has a simple structure, small overall dimensions, is easy to machine and install, and offers 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 commonly used materials for the metal tube. Nickel tubes are completed using electrodeposition.
