Unwind and Rewind Applications

Strong and versatile, Tidland Lug Shafts deliver superior performance in the widest range of converting
applications. Unmatched for positive holding power, the lug-style design eliminates core damage, prevents roll slip
through fast startups and shutdowns, and minimizes vibration at high web speeds. Simple modular construction and standardized components mean quick off-the-shelf spares service and easy in-plant maintenance when necessary.

Series 500 Lug Shaft - Air
The Series 500 Lug Shaft is designed for light- to heavy-duty applications in 50.8 mm (2 inch) to 152.4 mm (6 inch) ID cores; often used in center unwind and rewind applications with either fiber or steel cores. These reliable shafts are constructed of alloy steel, aluminum, or lightweight, composite materials – depending on usage and requirements.

Series 550 Lug Shaft - Mechanical
The Series 550 Lug Shaft is designed for medium- to heavy-duty in 76.2 mm (3 inch) ID cores; often used in center unwind and rewind applications with either fiber or steel cores. The shaft body is constructed of 4150 heat treated steel or lightweight, composite materials. Each shaft is built to order and has as much as 85% fewer moving parts than other mechanical shafts.
