Laminar Sealing Rings for Rotating Shafts and Housings 881276

Laminar Sealing Rings as grease seals and dirt excluders for rotating shafts and housings have been used in Europe for more than 30 years.
They form a highly efficient labyrinth seal that is virtually non-contacting, and therefore produce hardly any friction, heat or wear; their nearly unlimited temperature and speed-range, high reliability, minimum space requirements and insensitivity towards end-play and eccentricities allow the use of Laminar Sealing Rings for a wide variety of applications.
This paper covers the use of Laminar Sealing Rings as grease seals and dirtexcluders/protectors of elastomeric shaft seals for rotating shafts and housings and intends to give the designer an introduction to this sealing element.
