Abstract
A lubricant seal having no wearing surfaces is provided with a partition plate having a gutter portion and a slinger supported in a labyrinth cavity. This lubricant seal is particularly useful in larger seal applications where the wear of the rotating shafts exceeds the wear characteristics of available seal material. Migrating lubricants are captured in the gutter portion of the partition plate and are directed through the gutter portion around and below the shaft where the lubricant is returned through a drain to a sump.
