Our company KBK Antriebstechnik Gmbh was founded on July, 2nd, 2003.
The vision of manufacturing high quality products at competitive prices made us becoming the supplier of a steadily growing number of satisfied customers.
In our products you can find a more than twenty years lasting experience of developing and manufacturing couplings and locking devices which we offer combined with our advisory service and technical expertise.
The beneficial geographical position of our company near the Frankfurt airport and an excellent road network assure our customers worldwide deliveries within the agreed time.
Use all our strengths as well as our big motivation to even exceed our customers demands to save costs and time for your company!

We are manufacturers of backlash-free couplings / torque limiters, metal bellows couplings, vibration dampening elastomer jaw-type couplings,  miniature couplings, flexible servo couplings, line shafts / intermediate shafts as well as locking devices / power locks and shrink discs for hollow shafts.
