Type L Labyrinth Seals

Protection From Regular Contamination & Splashing Liquids

GMN Labyrinth Seals are non-contact seals that are designed with a maze-like path that traps contaminants and splashing liquids. The seals provide protection to the high precision bearing while in operation.

The L Type Labyrinth Seal has no outer ring grooves, like the M Type Labyrinth Seal, but has a similar labyrinth “maze” that centrifuges out liquids, dust, and dirt.
