Integrated COMBI Seal for Mud and Temperature Cycling | Heat-Resistant Contamination Protection

Temperature changes affect both the sealing lip and the mud around it. Heat can soften or age an unsuitable elastomer, while cold can reduce flexibility and increase the effect of packed contamination. A standard oil seal may fail even faster when temperature stress is combined with grit and water. The integrated COMBI seal adds external exclusion barriers, but the elastomer must still match the actual operating range and lubricant. NBR, HNBR and FKM options can be considered depending on duty. For reliable selection, provide minimum and maximum temperatures, shaft speed, pressure, oil type, contamination level and thermal cycling frequency.

Description

Temperature changes affect both the sealing lip and the mud around it. Heat can soften or age an unsuitable elastomer, while cold can reduce flexibility and increase the effect of packed contamination. A standard oil seal may fail even faster when temperature stress is combined with grit and water. The integrated COMBI seal adds external exclusion barriers, but the elastomer must still match the actual operating range and lubricant. NBR, HNBR and FKM options can be considered depending on duty. For reliable selection, provide minimum and maximum temperatures, shaft speed, pressure, oil type, contamination level and thermal cycling frequency.

Temperature and Mud Must Be Solved Together

A stronger dirt barrier cannot compensate for the wrong elastomer. The COMBI seal architecture protects the oil lip from contamination, while compound selection handles heat, cold and lubricant compatibility.
