Machines with offset drives are often thought of as insensitive to angular errors between driving and driven shaft. However, they cannot absorb angular misalignment between the shafts and conventional alignment methods cannot provide the needed level of accuracy. When using the Fixturlaser NXA together with the Fixturlaser Offset kit, you can precision align any offset mounted machine as fast as you would align any other shafts. The Fixturlaser Offset kit consists of both software and fixtures.

NXA Offset alignment of cardan shafts

why align cardan shafts?

Cardan shafts with angular misalignment typically cause the driven shaft to rotate unevenly during operation, which results in increased vibration. In other words, it is just as important to align cardan shafts as regular shafts. Why is that?

  • A vital part in drives for machines, where breakage of cardan shafts causes downtime
  • Badly aligned cardan shafts set limitation in production capacity and product quality
  • Stands for a considerable cost when a repair is needed or a breakdown occurs
  • Badly aligned cardan shafts reduce lifetime in gearboxes and motors
  • Breakdown of a cardan shaft in running condition could be extremely dangerous


This video shows how to use the cardan brackets and software to accurately measure and correct the angular misalignment that can cause problems for offset shaft driven machinery.


Fast mounting and measurement with the FIXTURLASER NXA Offset!

The Fixturlaser Offset NXA fixture is equipped with a laser pointer, which means that the alignment system is not needed in order to mount the fixtures. The fixtures only have to be adjusted until both the lasers are hitting the center of the opposing target. Thanks to this feature, the mounting can be performed fast.


The Offset fixture comes with a number of 
methods of attachment. The system is designed
so you can, in most cases, utilize the coupling
bolts themselves when mounting the arm on
the flange.
The Offset laser fixture is adjustable in a plane
parallel to the flange face of the stationary 
machine and can be set at any position to 
eliminate the offset from the driven unit.
The built-in lasers in each turret are pre-adjusted
so the laser beam represents the axis of rotation 
for the unit, it is mounted on.
The Clock method is used to get the result. In
the Clock method, machinery positions are 
calculated by taking three points with 180 degrees 
of rotation.
