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. The secondary function of a rotary shaft seal 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.
