Lip type shaft oil seals are widely used in rotary screw airends and come in a variety of designs and materials. This seal functions to retain the oil inside the airend, but also to keep air, dust and dirt from sucking in along the rotating shaft when the machine is off load. (When the inlet valve closes, if the airend continues to rotate, a vacuum may be pulled on the inlet end.)
