Radial Shaft Seals in Arctic Conditions

The sealing system of lip seals was studied at sub-zero temperatures. The gripping phenomena occurring between the lip seals and the shafts were investigated by simulating various field conditions. The breakaway torque was used to estimate the risk of failure for different conditions. The cause of the gripping phenomena between the seal lip and the shaft caused by the oil/water suspension was identified and its developing mechanisms were determined.
