Function

Rotary seals are designed to seal the pressurized fluid against the atmosphere, preventing leakage and pollution of the environment or to transfer liquids and/or gases from a stationary part into or out of rotating machinery.

Features

• The profile is designed with interference on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
• Tight seat in the housing and an additional retainer ring in hard plastic or Aluminum/Steel ensures that the seal is held in place.
• Tension spring for increasing the bonding force.
• Not suitable for high pressure from the trailing side.

Application

Pumps, electric motors, swiveling cylinders, etc.
