Simmerring  seal rotating shafts reliably and are used in millions of applications and a variety of equipment in general industry and the automotive sector. This radial shaft seal ring is based on know-how gained from years of experience. It continually undergoes further refinement based on the latest technological developments, and is particularly functionally reliable, flexible and extremely stressable.
Rotary shaft seals provide sealing and wiping functionality for rotating and swiveling movements under low pressure and high velocity. They perform two essential functions: the primary function is to retain the bearing or system lubricant in the system to avoid leakage, and the secondary function is to preclude any contamination of the system by external particles or other environmental impacts. Radial shaft seals typically consist of a metal insert and an elastomer diaphragm with a spring-energized sealing lip.
