Pneumatic shaft with friction rings

A shaft guaranteeing the winding tensions in multi-spools

Designed for the constant torque winding of several reels on the same shaft, despite variations in the thickness of the product to be wound. Its design allows, on the same axis, the rotation at different speeds of all the coils. Possibility of working with very small coil widths (11mm). It can be fitted with a rotating joint to enable winding at constant tension. Its maintenance is facilitated by the use of standard and interchangeable drive rings. The custom design and manufacture of the shafts allows the perfect match with your needs and in particular your torque, load and speed constraints. The range of DCI-type expandable shafts allows the use of chucks with diameters varying between 40 and 250mm.
