Cage bearings that allow more balls to be placed around the knife pivot than standard cage bearings. Which provides more support for the blade and decreasing stress on each ball. The ceramic balls are captured in the disc but are still free floating to prevent binding.

The ABB Corporate Research Center in Sweden is located in Västerås, about 100 kilometers west of Stockholm. Together with our colleagues in other R&D centers, we develop technologies for future products and services for ABB's core businesses.

Got these to replace the caged steel ball bearings in my pocket knife. I like that the balls can shift to both sides of the bearing instead of only one side. I also like that the balls are ceramic so they should not deform or wear down. I will be buying more and recommend them to anyone looking for smoother action on their knives.

We collaborate with universities around the world, including MIT, Carnegie Mellon, Rensselaer Polytechnic Institute in New York, KTH Royal Institute of Technology in Stockholm, Chalmers University of Technology in Gothenburg, Linköping University, Mälardalens University in Västerås and Uppsala University.
