Encoder applicationsHere you will find backlash-free couplings for sensors, encoders and tachos. Low restoring-forces to protect the sensitive encoder bearings is one of the key features for encoder couplings.
Servo applicationsCouplings for servo applications feature high precision and high torsional stiffness. Mostly made of light-weight aluminium to ensure a low mass of inertia.
Vacuum applicationsCouplings for applications in vacuum conditions and environments are mainly made of stainless steel or use low outgassing materials.
Micro applicationsHere you will find couplings with minimised outer diameters (<14 mm) and for smallest shaft diameters.
High-temperature applicationsHere you will find couplings for temperature ranges up to 300°C.
Heavy-Duty applicationsRoll-forming machines or presses are typical examples of applications with highest torque requirements. Here you will find couplings with torque transmission capacities of >1KNm.
Torsionally-stiffThe torsional stiffness of a coupling is defined as a spring rate and specified as a torque per unit deflection (Nm/rad or Nm/°). Torsional flexibility, the lack of torsional stiffness, will cause a loss of translational accuracy since the coupling winds-up. Torsionally-stiff couplings are transmitting torque pecisely and important f.e. for applications looking for positional accuracy.
Backlash-freeHere you will find backlash-free couplings. They ensure a backlash-free transmission even under highly-dynamic reversing conditions. They feature press-fit clamp-hubs or locking-assemblies.
High rpm applicationsHere you will find couplings for high-speed applications.  Light-weight aluminium and balancing features create couplings capable of speeds ranging from 6.000 up to 42.000 RPM.
Vibration-reducingHere you will find couplings with spiders or other functional elements (double loop) made of polyurethane or hytrel material. The couplings are able to dampen impulse loads while minimising shock to the motor and other sensitive equipment.
Electrically-isolatingHere you will find couplings having the advantage of electrical isolation due to the non-conductive nature of the center disk (Oldham) or other functional elements. This prevents electrical currents from being passed to delicate instruments which can cause inaccurate data readings or damage.
Axial plug-inCouplings in pluggable three-piece design allow an axial plug-in installation.
High angular misalignmentHere you will find couplings that can accommodate a high amount of angular misalignment >2°.
High radial misalignmentHere you will find couplings that can accommodate a high amount of radial, parallel misalignment.
Corrosion-resistantHere you will find couplings with hubs and/or other coupling parts are manufactured in stainless steel for increased corrosion resistance.
Fail safeHere you will find couplings which are considered fail safe because if the middle element were to fail, the hubs interlock for direct power transmission, allowing the application to be safely shut down for maintenance.
