• Bellows encoder coupling

    Shaft encoders must be connected to operated shaft and protected against excessive mechanical stresses, which occur whenever there are angular, axial, or radial misalignments between the machine and encoder shafts. At the same time the coupling needs to compensate for displacements without any big forces and positioning loss affecting the components of the encoder. Our flexible couplings can compensate for this within limits. Bellows coupling usually compensate higher misalignment.

  • Bellows encoder coupling LIR-825

    Shaft encoders must be connected to operated shaft and protected against excessive mechanical stresses, which occur whenever there are angular, axial, or radial misalignments between the machine and encoder shafts. At the same time the coupling needs to compensate for displacements without any big forces and positioning loss affecting the components of the encoder. Our flexible couplings can compensate for this within limits. Bellows couplings usually compensate bigger shaft misalignment. LIR-825 suitable for most industrial encoders with solid shaft diameters 4 to 12 mm.
