Rulon 142
聚四氟乙烯
Saint Gobain Performance Plastics

产品说明

Rulon® 142 is a specially formulated dull bluegreen 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.
