HRB vs. ACBBs

ALT BEARINGS have published comparisons of load capacities and life spans of the HRBs, for all ranges, against those of stacks of ACBBs (Angular Contact Ball Bearings) having the same size. These comparisons, freely available and downloadable on the website, shows how performant HRBs are especially when it comes to service lifetime. It worth mentioning that ACBBs used for these comparisons are from the best competitor in traditional bearings manufacturing.
