Tidland External Element Air Shaft

• 
• 

Series 800 shafts feature innovative two-piece expanding elements, which deliver an impressive combination of balance and torque. These advanced shafts also feature 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 800 Strip Shaft is designed for medium- to heavy-duty in 76.2 mm (3 inch) to 508 mm (20 inch) ID cores. This shaft’s full-length strip design delivers excellent torque characteristics, making it ideal for general duty unwind and rewind applications.

Key Features

Advanced external element design delivers superior roll build quality
Two-piece element design is resistant to punctures but can be changed easily, without removing the shaft from the machine
Isolated air circuits insure core is held even if one element fails minimizing downtime
Durable construction designed to withstand abuse and abrasion
Rubber or metallic expansion elements support a wide variety of converting applications and core materials
