Aerospace Bearings - Cryogenic

Turbine Flowmeter Cutaway with PKB Cryogenic Ball Bearings Installed

PACAMOR KUBAR BEARINGS (PKB) extremely high precision cryogenic bearings are found in many challenging aerospace applications, including life-sustaining survival suits for space exploration, public and private rocket launches and well known NASA space projects. PKB cryogenic bearings are found in space vehicles, guidance systems, array mechanisms, flow meters and flow control units.

Pacamor Kubar Bearings (PKB) manufactures cryogenic bearings for flow meters, flow control units, air calibration for many types of gasses and liquid cryogenic applications. Certain liquid cryogenic liquids such as LIN, LOX, LAR, LH2 and others require special ball bearing materials and design considerations, which PKB is able to provide. To meet the unique challenges encountered by bearings used in flow control and flowmeters that work in extreme environments, the PKB engineering team designates special design features for maximum performance.
