CONTROLLED GAP SEAL 560168

The Controlled Gap Seal consists of a carbon sealing ring with a steel retaining ring shrink fitted on the outside diameter, two steel mating rings, a spacer ring, and an outer shell.
In operation under ideal conditions there is a pressure differential across the seal with the air side pressure being higher than the oil side. This differential prevents oil leakage and holds the carbon sealing ring against the oil side mating ring while the shaft turns freely within the sealing ring.
The Controlled Gap Seal will operate with unlimited axial movement, is of rugged construction and will give long life and very low heat generation. It is good for high temperature operation since there are no rubber or plastic materials used.
