PKB manufactures cryogenic bearings for the involvement of 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 customer design considerations, which Pacamor Kubar is able to provide. PKB engineering processes these special design features for maximum performance and reliability.

PKB is a trusted name in high-precision OEM and replacement miniature ball bearings for commercial, private, and military aircraft and aerospace systems.

For high-speed bearing applications, bearing noise, vibration, and bearing life are all important factors considered in the manufacturing process.

We produce all of our bearing rings out of 440c Stainless Steel but don’t hesitate to inquire about other materials. We also offer multiple retainer materials and specialty ball materials, coatings, and closures, to meet the specific requirements of your application(s). Our miniature and specialty ball bearings are available in standard inch sizes and various metric sizes.
