LABRINTH SEAL

For applications where there are high speeds and/or extreme temperatures a labyrinth type seal can be used. Labyrinth seals consist of a metals ring with two steps arranged radially. One step fits into the seal groove in the housing to form a gap type seal and the other step forms a gap type seal with the outside of the housing, A hollow silicone tube supplied with the seal holds the labyrinth in place when the shaft is rotating, labyrinth seals are designed to rotate with the shaft and they can also accommodate misalignment of  up to 0.3 degrees.
