Labyrinth Seals & Rings

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.
