142 / 142S / 242 PTFE

Rulon® 142 / 142S / 242 materials are specially formulated dull blue-green linear bearing formulations that exhibit low wear, high thermal dissipation, and good dimensional stability characteristics. They are metal-filled polymer material solutions used for dimensional stability, vibration, and wear resistance.

Among their many benefits are the virtual elimination of stick-slip, vibration dampening, self-lubrication, uniform friction, long life, ease of application, and design diversity. They are low deformation materials suitable for linear bearings and slides.

Rulon® 142 / 142S / 242 formulations have excellent mechanical properties and are the ideal materials for machine tool applications. Their 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.
