Commercial Instrument Bearing Applications

With over forty years of miniature and instrument expertise, chances are you've been relying on PKB instrument bearings in many of the products you use everyday.

Computer disk drives spin with our precision instrument bearings as an integral component.

With PKB instrument ball bearings installed in your products, you can be confident that your device contains high quality, reliable, and domestically produced components.

Our customers' requirements range from small volume, customized products to high volume standard products and everything in between. We understand that manufacturers demand reliability and value in every purchase, which is why we offer a range of designs and materials. Whether your application is a high intensity laser or a home computer disk drive, PKB offers the right instrument bearing at the right price for nearly every application.

Bearing Design

Pacamor Kubar Bearings offers a range of retainer designs and materials including: Crown, Ribbon, heat and moisture resistant Phenolic, and Torlon (polyamide-imide). In addition to selecting the right retainer for your commercial application, dissimilar materials can prevent metal to metal welding and extend the life of the bearing in a variety of applications. To this end, we offer standard 440C stainless steel or optional ceramic balls or titanium carbide coated 440C stainless steel balls in our instrument bearing designs.

PKB miniature and instrument bearings are available with up to ABEC 9 tolerances (as defined by the American Bearing Manufacturers' Association) with an optional flanged outer ring.

Our commercial instrument bearings are supplied ready for use, complete with your choice of bearing lubricant.
