What are Labyrinth Seals? GMN provides Labyrinth Seals (also called Labyrinth Rings) which are non separable units of a steel inner ring and an aluminum outer ring ready for installation. Due to the very special production process both rings carry absolutely identical profiles which result in the perfect gap between both rings.
The dimensions of the Non-Contact Seals are equal or close to the dimensions of anti-friction bearings and regular contact seals.
The "M" Type labyrinth seals
incorporate milled grooves at the outer ring to allow heavy splashing liquid particles to be
centrifuged out into an annular groove in the customer's part which is connected to a drain
hole. These penetrating liquids can then be led back to the desired location.
Diameter range (shaft) d = 15 mm to 210 mm
Width - depending on size 10 / 14 / 15 / 20 / 22 mm
for fine and coarse granular contamination
for heavy splashing liquids
no speed limit
maximum temperature 170° C/340° F
