Labyrinth Seals

Custom-Engineered for Efficiency

Labyrinth seals are a critical component applied across rotating equipment to seal high pressure areas from low pressure areas and prevent contamination of the process. Designed as a non-contacting seal with a precise clearance over the rotor, labyrinth seals directly affect equipment efficiency.

As with all Bearings Plus solutions, our labyrinth seals are custom-engineered for each application. Design factors include seal arrangement, operating temperatures, pressures, speed, process make-up, and thermal expansion, among others.
