| The PolyLube Glass Tape bearing can withstand static loads of approximately 40,000 PSI and 7,000 PSI under dynamic loading. At these loading levels, minimum distortion will occur. For dry running applications, the maximum speed is approximately 300 surface feet per minute. This bearing’s operating temperature range is ±325°F. Maximum continuous operational surface temperature for the standard formulation is 325°F, depending upon load characteristics. The bearing has been heat stabilized at these temperatures, so that little dimensional change will occur in the bearing during operation. In a free state, the coefficient of expansion of the PolyLube Glass Tape bearing is approximately 7 x 106 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals. Applications: Applications for PolyLube® Glass Tape Bearings range from guide rod bearings to linear motion components to hydraulic pumps. Swashblock mounted bearings are ideal applications for the Glass Tape bearing material as long as application considerations are consistent with a mixed film condition. 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. Information provided by Polygon |
