Series 850 takes our innovative two-piece expanding elements to a whole new level. The unique spiral design of the Series 850 provides a continuous 360º of radial grip and intrinsically equalized load distribution. These advanced shafts also feature a two-piece body design, self retraction, durable poly bladder, and a fail-safe multi-circuit air system, with check valves to ensure that a loss of air in one element will not affect the expansion and performance of the other elements.
The Series 850 Spiral Strip Shaft is designed for medium to heavy-duty in 75 mm (3 inch) to 406 mm (16 inch) ID cores. The spiral strip design of this shaft minimizes vibration to deliver smoother operation and higher speeds. It's an ideal choice for surface winders or with lay-on rolls.
