Rotary seals, the best mobile connection between mobile elements
Rotary seals are used for rotating components, that is to say, then a mobile connection is needed between elements which are mobile. The purpose of rotary seals is twofold, on the one hand they prevent lubricating fluid from escaping, and on the other hand they prevent water, dust, or mud entering. This type of seal is operative in a wide range of temperatures and pressures.
You have all the information that you will need below about rotary seals, (CB with spring, CB without spring, CC, BB, BC, DB, DC, PC for pressure, HP, VA, VS…), including their type, profile, the material in which they are manufactured, as well as the pressure, temperatures, and speeds which they can withstand.
