RBI provides quality mounted and unmounted ball and roller bearings that are used throughout industries worldwide. We manufacture a full range of popular bearing types. Our bearings are available in 52100 high carbon bearing steel and 440C stainless steel. RBI’s bearings meet ABEC 1 precision grade and use grade 10 precision balls to provide smooth running and quiet operation. Common high temperature lubricants and food grade greases are available. RBI’s ball bearings can be provided open, with seals or steel shields. We realize standard off-the-shelf bearings don’t work for every situation; we often produce custom bearings for our customers according to their drawing specs to fit a variety of applications.
