Glass Tape wear surface provides reduced stick slip and smooth motion, especially in lower pressure applications. A great example of this is when the bearing movement is primarily axially (along the length of the bearing), such as in cylinder guide rod bearings. Use it in a bearing that will perform at a moderate RPM for applications with higher surface velocities or when mixed film conditions are desired. Glass Tape is manufactured by a filament winding process that results in a continuous fiberglass filament backing composition, which ensures excellent mechanical properties, especially fatigue resistance.Applications for PolyLube Glass Tape Bearings range from guide rod bearings to linear motion components to hydraulic pumps. The PolyLube bearing offers a more elastic, damage tolerant structure when compared to traditional metallic bearing materials. In addition, the Glass Tape bearing exhibits good cavitation resistance when subjected to high pressure fluids during cyclic conditions
