| The PolyLube® MRP bearing can withstand static loads of approximately 70,000 PSI and 30,000 PSI under dynamic loading. 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 MRP bearing is approximately 7 x 106 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals. Applications: PolyLube MRP bearings are the bearing of choice in highly loaded bearing joints where a life cycle of over 500,000 cycles is desired. Testing has shown this bearing has wear under 0.006" after 1.6 million cycles. Applications include material handling equipment, high duty cranes, earth-moving equipment, construction equipment, agriculture equipment and food processing systems. MRP bearings have extremely low absorption rates and are well designed for wet and submerged applications. Information provided by Polygon |
