Metal Bellows Coupling I Series KXL for high torques up to 70.000 Nm backlash-free, exact torque transfer high torsional stiffness low moments of inertia high tolerance of shaft misalignments three-part construction easy to fit variable in use The metal bellows couplings of the series KXL are constructed for medium size to big drives of up to 70.000 Nm. Although this type of coupling has proven itself reliable for years, the series was completely redesigned in order to make it even more attractive regarding technical parameters as well as the aspect of costs. It is very special because of the three-part construction with a flexible intermediate piece (bellows). This intermediate piece can be disassembled. It consists of an optimal torsionally stiff stainless steel bellows with 2 bellows shafts on each side and an intermediate pipe which is variable in length. The connection with the two hubs is frictionally engaged (screws acc. to ISO 4017/10.9). Therefore, assembly is much easier, as in case of inspection or service, the heavy drive unit or the output unit need not be disassembled. The designer can choose between several hub variations (see selection table). The very good moment of inertia and the rotation symmetrical design ensure good dynamic operation characteristics. KXL couplings are most suitable for precise drives, such as those used in printing machines, cross cutters, main spindle drives, transfer axes or used in combination with gearboxes. Medium transport or a parallel drive chain through the coupling interior is possible. material: bellows: stainless steel flange: heat-treated steel - oxidized hubs: heat-treated steel - oxidized nominal maximum torsional torque torque stiffness CT spring rate maximum temperature range: -40°C up to +300°C per hub per hub per hub per hub bellows bellows A/B F/G A/B F/G JA/JB JF/FG JBP mA/mB mF/mG mBP [kg] [kg] [kg] [kgm2] [kgm2] [kgm2] 8 12 16 21 31 52 95 note: The technical data corresponds to bellows with standard length ‘L16’ or ‘LA’.

hub type A: frictional, backlash-free conical clamping ring connection, external free lateral disassembly of the bellow part. The elongation of total length “L4” of the intermediate pice of 4 mm at mounting is already taken into consideration (see mounting picture) hub type B: frictional, backlash-free conical clamping ring connection, internal free lateral disassembly of the bellows part is NOT possible hub type F/G: attached flange acc. to ISO 9409 or customer requirements center outside or inside.
