SUMMARY
The discussion focuses on the performance limits of Simmerring seals, specifically for a shaft with a diameter of 20 mm rotating at 1370 rpm and a circumferential speed of 1.5 m/s. The materials analyzed are NBR (Nitrile Butadiene Rubber) and FKM (Fluoroelastomer), with performance regions defined in a referenced graph. Users can safely utilize NBR in the light gray region and FKM in both the light and dark gray regions, while neither material is suitable in the blue region.
