Metric Oil Seals for Complex Industrial Applications

Oil seals are very important components for the successful operation of a wide variety of industrial and commercial equipment. They are used to seal the gaps between stationary and moving parts in mechanical equipment, while keeping the lubricant from escaping.

They also prevent dust, dirt, and other contaminants from getting into the machinery. Oil seals also keep dissimilar fluids like oil and water from mixing with each other.

Accurate and Tighter Sealing with Metric Oil Seals

Metric oil seals help ensure that the valves, cylinders, hydraulic rods, and piston rods don't leak pressurized fluids. Metric oil seals are sized metrically according to the European metric system of measurement.

The size of these seals is stamped on the seal for easy identification. Metric sizing is a more accurate than linear sizing. This allows them to deliver a tighter, and more effective sealing around the application.

Metric Oil Seals by SSP Manufacturing Inc.

SSP Manufacturing Inc. manufactures and supplies metric oil seals for various industrial applications. Our seals are manufactured using various compounds and materials to suit a variety of application environments. Commonly, used materials include:

  • Ethylene-acrylic
  • Tetrafluoroethylene propylene
  • Polytetrafluoroethylene (PTFE)
  • Urethane
  • Polyacrylate
  • Fluor-elastomer
  • Nitrile
  • Leather
  • Silicone


Construction Characteristics of Metric Oil Seals

The characteristics of metric oil seals used in various industrial applications are explained below:

  • The outer skin of the metric seals is made from one of the flexible materials mentioned above.
  • An interior metal ring provides structural stability to the seals.
  • Metric oil seals have a lip that rubs against the rotating shaft. It prevents the lubricant from leaking.
  • A spring supports the lip, and keeps it in contact with the shaft.

Applications of Metric Oil Seals:

Metric shaft seals are installed in practically every type of machine including industrial motors, pumps, vehicles, engines, etc. Major applications of metric oil seals include:

  • Differentials
  • Timing covers
  • Industrial gearboxes
  • General and special machinery
  • Shredders
  • Camshafts
  • Input shafts
  • Crankshafts
  • Axles
  • Bailers
  • Pinions
  • Wheels
  • Crushers

Industrial metric oil seals are available in various sizes and lip patterns. Also, they are designed to suit specific temperature and pressure ranges. Therefore, it’s crucial to know which seal can be suitable for your machinery. The experienced staff at SSP Manufacturing Inc. can help you in selecting the type of seal best suited for your project.
