Backlash-free Flender couplings facilitate high positional accuracy

10 October 2015

Siemens has augmented its portfolio of couplings with the addition of the new backlash-free Flender Bipex-S and Flender Sipex couplings.

Both coupling versions can be used in production machines and machine tools, as well as in automation engineering. They are available in various sizes and can be installed in integrated drive systems, frequently in combination with servo motors.

Bipex-S torsionally flexible elastomer couplings are used in applications subject to vibration and shocks; Sipex metal bellows couplings are used in drives that require an absolutely angle-preserving torque transmission.

Bipex-S couplings offer high power density and electrically isolating properties that protect against leakage currents. They enable a high degree of positional accuracy and reduce the wear on the system through lower peak loads and vibrations. The axial plug-in enables blind assembly. If the elastomer wears away completely, the jaws of the coupling hubs provide emergency running properties.

The extremely torsionally rigid Sipex couplings facilitate angle-preserving torque transmission, which consequently provides the highest positional accuracy. They are non-wearing and maintenance-free, reduce unplanned system and machine downtimes which, in turn, increases system availability. 

The true-running properties of the couplings make them particularly suitable for high speeds. Low restoring forces, almost no bearing load in the coupled machines and a good power density round off their positive properties.

The new couplings are each available in six hub versions.
