deep groove ball bearing We uses good quality vacuum desigassing sttel GCr15 as ring material, this tyape of steel has been vacuum smelt,and the oxygen conten and the impruity contend has been largely reduced,after special heat tretment process,the ring can suffer relatively heavy contact stress and Alernate stress,so that the using lifespan of the bearing is extanded largely. This type dearing nature is High Hardness,High Abrasiveness,High Con tact fatigue strength,Certain impact toughness and Fracture toughness,Good Dimensional stability,Good rust protection.
