Installing Radial Shaft Seals

Radial shaft seals, also known as lip seals, are used to seal rotary elements, like a shaft or rotating bore. Hydraulic pump seals, axle seals, valve stem seals, or strut seals are the most common examples the average person would recognize.

Radial shaft seals are used in a variety of applications and perform two essential functions: the first is to avoid leakage through retaining the bearing or system lubricant; the secondary function is to avoid the contamination of the system by outside impacts (external particles or environmental issues).

Radial shaft seals are manufactured in an assortment of sizes, but many of these specialized seals are larger than average (e.g. windmill turbines use seals up to 4,000mm in diameter) and are used in nearly every industry:

  • Agriculture
  • Automotive
  • Construction
  • Distribution
  • Fluid Handling
  • Fluid Power
  • Food & Beverage
  • Material Handling
  • Power Generation
  • Power Transmission
  • Railway.
