Mechanical expanding shafts with lugs mod. 635 MK


Mechanical expanding shaft with lugs model 635 MK is primarily recommended for unwinding and winding rolls that have cores.

The body of the shaft is available in a variety of steels; the expanding lugs come in either steel, plastic or rubber covered depending upon core material and torque requirements. The journal ends are also available in a variety of steels 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.
