636 MS - Mechanical expanding shafts with leaves

The Model 636/MS is recommended for winding or unwinding rolls with and without cores.

It can be used with multi-slits also for very narrow web widths. The body of the shaft is available in steel or aluminum and the expansion leaves are available in steel, aluminum or with rubberized surface, depending upon core material and torque requirements. The journal ends are also available in a variety of materials and are always custom-made. Expansion is accomplished by a square socket located in the end of one journal; the positive expansion and retraction that is gained results in self-centering of the roll and the ability to handle higher torque requirements.

Standard sizes available for this Model are listed below.

• Core diameter from 60 to 300 mm.
