Flexible couplings

Flexible couplings are usually used to transmit torque from one shaft to the other when the two shafts are slightly misaligned. Furthermore, a flexible coupling can protect the driving and driven shaft component from the harmful effects of conditions such as misaligned shafts, vibration, shock loads, and thermal expansion. This type of coupling is suitable especially for drives with uniform to average dynamic loads. Examples of applications are pump drives, ventilator drives or crane running gear.

Highly flexible couplings

Due to their low torsional stiffness and good damping capacity, highly flexible couplings are suitable for connecting non-uniformly working machines with high shaft misalignment. An additional plus is the capacity of noise reduction, electrical insulation, as well as compensation of periodical excitation and thermal expansion. Examples of applications are roller tables, pumps, or compressor drives.

Backlash-free couplings

With their high torsional stiffness and ability for angle preserving torque transmission our compact backlash-free couplings are able to achieve the highest positioning accuracy. After the easy installation they are almost completely maintenance- and wear-free and can therefore assure the durability of your drive applications. They are especially suitable for positioning drives, stepping motors and linear units in a wide range of application fields.
