Rulon 142 is a specially formunlated dull blue-green linear bearing material that exhibits low wear, high thermal dissipation, and good dimensional stability characteristics. Among its many benefits are the virtual elimination of stick-slip, vibration dampening, self-lubrication, uniform friction, long life, ease of application and design diversity.

Rulon 142 has excellent mechanical properties and is the ideal material for machine tool applications. Its low deformation characteristics limit the amount of misalignment that can occur with other bearing materials. Strong acids and bases should be avoided, as they may attack the fillers.








Walle have many years production experience and industry field application experience, we aimed at the different harsh sealing environments and developed various of materials suitable for applications. Improving all customers profit and saving all customers cost. Walle automatic production equipments and advanced testing equipments provide a strong guarantee for the manufacture of high quality PTFE-based material seals.
