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.

  • Shaft Diameter (d) (mm): 15 to 210
  • Outer Diameter (D) (mm): 26 to 250
  • Width (mm): 10, 14, 15, 20, 22
  • Max Temp: 340° F (170° C)
  • Protection Type: Good for Fine or Coarse Contamination
  • Liquids: Suited for Normal Splashing Liquids
  • Max Speed Limit: None
