Self Aligning Type Welding Rotator automatically adjusts the Roller Housings to accept any job diameters within the specified diameter range.  These types of Self Aligning Type Welding rollers are generally used to cope with the increased production demands.

The roller housings of this type of machine are hinged to the beds and open up automatically when a larger diameter job is introduced.

In the Self-Aligning Type Welding rotator, each Roller bracket assembly has two separate roller assemblies, and this supports the job in a wider area. The final drive is given to all the sets of rollers of the Drive Unit in special models, providing better traction to the job.

However, in that case, a de-clutching arrangement is provided to the top rollers, in order to protect the gearboxes, as when the job hits the top rollers first while loading, forcing it to rotate via. The self-locking gearbox.
