Bellows shaft couplings are an ideal choice for applications that require high dynamic positioning, such as servo drives.
They are characterised by their zero backlash operation, high torsional strength and low restoring forces. Our range of Bellows Couplings cover shaft diameters from 1mm up to 100mm, and torque ratings ranging from 0.5Nm to 5000Nm.
Bellows shaft couplings can be used in applications that require angular misalignment or parallel misalignment. The design delivers high torsional rigidity, due to the bellows' radial rigidity and low side thrust due to the bellows lateral flexibility.
Other coupling types have either low windup or low side thrust, but not both. Precision motion control applications require mechanically tight systems, especially between motors, driven loads, and feedback devices, to ensure accurate positioning. Such systems often require shaft couplings that are both torsionally rigid, to accurately transmit rotational position and laterally flexible to accommodate shaft misalignment.
Our range of Bellows Couplings cover shaft diameters from 1mm up to 100mm, and torque ratings ranging from 0.5Nm to 5000Nm. Some sizes are available with full stainless steel construction. Axial pluggable hubs are also available.
