KBK offer a wide range of modular high quality product systems at an affordable price. And KBK provides short delivery periods as well as the compliance with high quality management standards.

KBK safety/overload couplings are based on the ball-in-detent principle and they are absolutely backlash free due to the KBK-specific arrangement of the balls as locking element. Each safety coupling is adjusted and tested to the release torque requested by the customer. After the initial operation, the release torque can be adjusted continuously by the customer. KBK safety couplings are available in four different function modes and numerous versions for direct and indirect drives.

Metal bellows couplings are the first choice for all applications that require high dynamic positioning - the classic application in servo drives. They are characterized by an absolutely backlash-free function and high torsional strength. Maintenance –freedom, fatigue strength and low restoring forces with misalignment, top off the features of the bellow coupling. The KBK modular system allows an incomparable variety of options, which offer the suitable coupling for each assembly situation.

Elastomer couplings are the durable solution for positioning applications, wherever high torques must be transmitted in compact installation spaces. By means of elastomeric spider elements in different grades of hardness, the characteristic features of our claw couplings can be modified from vibration reducing to torsionally rigid – depending on the requirements. The pretension of the elastomeric spider elements in the jaws of the coupling allows a servo-ready, backlash-free version.

With KBK line shafts, high distances between shaft ends are no longer a problem. These line shafts are precisely manufactured with an accuracy of one millimeter according to the requested length. An extremely light and rigid precision tube made of aluminum contributes to the high performance. Therefore, it is the perfect solution to synchronize both linear units and lifting gears. This type, which is also called drive shaft, is both available as metal bellow and elastomer coupling – but we are also able to produce one-sided rigid versions or completely rigid versions.

For the permanent protection against frequent overload, KBK magnetic couplings are the right choice. They work absolutely wear free and for that reason they are of fatigue strength and maintenance-free. The simple connection by using clamping hubs and the quick adjustment of the overload torque via the insertion depth of the inner into the outer rotor, allow a fast and uncomplicated use. The following operating principles are possible: the permanent magnetic coupling, which starts „bucking“ in case of overload and the hysteresis coupling which slides similar to the sliding coupling.
