The requirements for ultrareliable miniature cryocoolers with affordable price is growing up for the military, space and commercial infrared applications. For scientific space application a MTTF in the range of 20,000 hours is targeted today by the potential users. To reach this goal, a technical breakthrough is necessary and a combination of an ultrareliable linear drive compressor based on flexure bearings and a pulse tube coldfinger is proposed. A technical description of the cryocooler is presented and a dynamic vibration control system is discussed.
