HSLA RB-80 steel used in Unground Bearing Outer Raceways
(OP)
Has anyone ever heard over unground bearings using outer raceways manufactured from HSLA steel. Any input appreciated. I have put forth alot of effort into actual life/load dynamic testing and comparing to standard bearings using low carbon grade steel stamped outer races that have been case hardened with basically no success even at 1/2 load rating applied to HSLA outer races. Bearings are running at 60 surface feet a minute for comparative testing, both grease and oil have been run still no success on HSLA. Heavy ball paths are worn into the HSLA. Thoughts anyone?
