Laminated cotton fabric tubes.
TUFNOL Rolled Laminated cotton fabric tubes were developed to complement the range of moulded tubes. RL tubes have good mechanical strength, low water absorption and are resistant to weathering and to chemical attack by mild acids and alkalis. They are most commonly used to manufacture mechanical and wear resistance components for a wide range of engineering applications. They are strong and rigid, with good bursting strength and excellent wear resistance in lubricated applications.
Three grades are available:
· Grade RL F/1 – A fine weave fabric grade with good electrical and mechanical qualities. Machines well and is suitable for finer and more intricate components
· Grade RL F/2 – A fairly fine weave grade, developed mainly for its good mechanical strength, but suitable for low voltage electrical applications.
· Grade RL F/3 – A medium weave grade giving improved wear resistance where surface finish and intricate machining are not required. Suitable for low voltage electrical applications.

What are TUFNOL RL Cotton Fabric tubes used for?
These materials are used for many applications where strong, rigid tubes are required for the manufcture of cylindrical components. Items include mechanical or wear resistant components, such as wear rings for hydraulic rams, lubricated bearings or ball race cages. Electrical insulation components are also made. |
