Type DI - internal seal

Type DI..

Internal seal for oil and grease

Axial shaft seal with internal sealing lip, for use with liquids under high pressure. This seal operates in accordance with the “knuckle action” princible, i.e. the pressure build-up on the medium side is partly reversed by the appropriately designed packing ring, thereby pressing the sealing lip against the mating surface.

A = contact pressure force
