• Rulon 142

    Rulon® 142 │ Exceptional for Linear Bearings and Slides

When you have a need for exceptional vibration resistance, superior mechanical strength, and good dimensional stability, consider the versatile Rulon142.  This low-deformation compound exceeds most materials in preventing catastrophic failures on machine tool guideways.  It is also our most cost effective linear bearing material.

Other key characteristics of the aqua-colored Rulon 142 are virtual elimination of stick/slip, uniform friction, high thermal dissipation, and good stability.  And like all variations of Rulon, Rulon 142 delivers long wear, self-lubrication, and design diversity.  

Ask the experts if Rulon 142 is right for you!
