Oil seals, also known as industrial shaft seals, are used to seal the opening between a rotating and a stationary component, or between two components in relative motion.

Primary oil seal functions include:
  • Retain the lubricant
  • Exclude contaminants
  • Separate two different media
  • Seal under pressure

To be effective, oil seals should operate with a minimum amount of friction and wear, even under unfavorable operating conditions. In order to meet the requirements of a variety of different applications and operating conditions, SKF oil seals, for rotating machine components, are manufactured in many different designs, materials, and executions. Each of these designs and material combinations has specific properties, making them suitable for a particular application.
