KBK Antriebstechnik offers a flexible modular system for different shaft couplings. Rigid shaft couplings for the fixed connection of two or more aligned shafts are standard elements in mechanical engineering. The frictional connections made of burnished steel are quick to install thanks to lateral clamping screws and can transmit high torques in a compact design. KBK offers the rigid couplings in all sizes and variants with stepped bores on request. The rigid shaft couplings in the KBST series are available in 13 sizes for shaft diameters from 6 to 50 mm and torques from 30 to 2250 Nm. In the KBST-G series, they are also available as a double-shell design. Thanks to the half-shell design, the coupling can be assembled and disassembled without moving the shafts. This coupling is available in 14 sizes from 5 to 50 mm shaft diameter for torques from 21 to 2250 Nm.
