Mechanical Expanding Shafts With Lugs
Mod. 635 MK
The 635 MK Mechanical Expanding Shaft with Lugs is primarily designed for winding and unwinding rolls mounted on cores, providing secure gripping and reliable roll positioning.
The shaft body is manufactured from various steel grades to suit different operating requirements. The expanding lugs are available in steel, plastic, or rubber-coated options, depending on the core material and the required torque. The journal ends are custom-made from different steel grades to meet specific application needs.
The expansion mechanism is operated using a square socket located at the end of one journal. This system enables controlled expansion and retraction of the lugs, ensuring firm core engagement and effective self-centering of the roll. Its robust mechanical design also supports higher torque requirements, making it suitable for demanding winding and unwinding applications.
