Below is a list of Rotary Seals manufacturers from Saint Charles, Illinois. Rotary seals are highly efficient lip seals that keep the components in rotating machinery and equipment working properly. They provide bearing protection, lubricant retention, exclusion of contaminants and minimize or eliminate the leaking of fluids. They are able to perform well for long periods of time with a high rotating speed and in temperatures anywhere from -60°F to 200°F. Rotary seals perform even in poorly lubricated and dry conditions.
