Rigid shaft couplings
Backlash-free transmission of high torques
Rigid shaft couplings from KBK not only connect shafts or shaft sections firmly and without play, they also transmit high torques at the same time. The couplings are therefore suitable for use in machine tools, conveyor systems and robot lines.
KBK manufactures the compact shaft couplings in four versions and numerous sizes that cover different shaft diameters and torque ranges. For example, the KBST can be used to connect shafts with diameters from 6 to 50 mm and transmit torques between 30 and 2250 Nm. The coupling is securely mounted with lateral clamping screws and, like all of the manufacturer's rigid shaft couplings, is also available with a continuous bore or with different bore diameters.
The KBST-G also transmits torques from 30 to 2250 Nm, but can be assembled and disassembled somewhat more quickly due to its half-shell design. The coupling can be used on shafts with diameters from 5 to 52 mm. The KBST-VA and KBST-G-VA series couplings are made of stainless steel and are therefore also suitable for hygiene-critical areas such as the food industry. Both versions transmit torques between 25 and 1875 Nm and are available in a half-shell design or in a one-piece version with a wide range of bore combinations. The KBST-VA is compatible with shafts with diameters from 6 to 50 mm, while the KBST-G-VA can be mounted on shafts with diameters from 5 to 52 mm. Thanks to its half-shell design, the KBST-G-VA can be fitted and removed without moving the shafts.
According to KBK, it is the only manufacturer to offer all four shaft coupling types with a wide variety of individual bores, which can also be combined with each other as required. The couplings are available with and without a keyway.
