They cover torque ranges between 0.1 and 60 Nm and are wear-free and easy to clean. The couplings are therefore ideal for use in the food industry and on packaging systems. KBK manufactures both hysteresis magnetic clutches and permanent magnetic clutches. The hysteresis magnetic couplings are suitable for use in the rotary heads of bottle capping systems for PET bottles. They prevent the bottle caps from being screwed on too tightly so that they can be easily opened by the consumer.

On the other hand, permanent magnet couplings from KBK are ideal for the rotating heads in capping systems for glass bottles: the jerky separation of the power transmission ensures that the bottle cap is tightly closed and a perfect seal is achieved.
