Servomotor bellows are for dynamic-sealing applications which are restricted by space limitations or where long life and reliability are critical. They can be designed for a variety of stroke and pressure combinations and for temperatures from -423 to 350F. Design manual contains formulas for designing miniature electrodeposited nickel bellows. A list of the 16 bellows available from stock includes data on the spring rate, compression stroke, and pressure rating.
