The "Toolflex CF"From KTR Kupplungstechnik can be used with very compact drives such as servo gearboxes. To save length, a hub with flanged connection is used in the backlash-free bellows coupling. The opposite side comes standard with the classic clamping hub, which can also be supplied as flange version on request. The toolflex CF is available in the size range 30 to 55. The power transmission of the flange hub, which is made of high-quality steel, takes place frictionally on the front of the hub. This is important to ensure that the coupling is free of play. The bellows is available in the lengths "S" as four-wave and "L" as six-wave bellows.
