The PKB ball bearing factory capabilities keep expanding. Here’s the latest! We’re making angular contact, radial, full-complement, miniature inch and metric, instrument, thin-section bearings, and bearings with specialty features and modified dimensions, plus an optional flange.   The PKB factory has further expanded machining capabilities, and is now able to include a flange on all bearing sizes, including our largest 1.125″ (28.57mm) OD bearings. 


Angular Contact bearings are available with relieved inner or relieved outer ring configurations and are built as either separable or non-separable assemblies. Many retainer material options are readily available for all designs. Contact us to discuss our wide range of popular and hard-to-find materials.   All bearing sizes are FAA TSO-C149 Aircraft Bearings and any of them can be heat treat stabilized for Cryogenic Applications


Cryogenic Stabilization

Cryogenic Stabilization, as part of our Heat Treat Process, has become a popular request from the aerospace community.

We’re pleased and honored to share a very nice testimonial, from the CEO of Hoffer Flow Controls, about the superior performance of PKB Cryogenic Bearings in their Flow Control Units.


Speaking of cold.  There are no snow days for us.  We’re here for you, even in extreme weather conditions.
