| The PolyLube® IFR backed bearing can withstand static loads of approximately 70,000 PSI and 30,000 PSI under dynamic loading. At these loading levels, minimum distortion will occur. For dry running applications, the maximum speed is approximately 10 surface feet per minute. The typical average design pressure for high duty cycle applications is 10,000 PSI. 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 IFR bearing is approximately 7 x 106 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals. Applications: Excellent applications for IFR backed bearings include bearing systems using alloyed bronze, spring-retained, hardened bearings and hardened steel bearings.
