Roller bearingshave a higher load carrying capacitythan ballbearings. Therefore, roller bearings, i.e. cylindricalroller bearings, tapered roller bearingsor sphericalroller bearings, become the automatic choice for carrying the radialloads. These bearingsare made of through-hardened rolling bearing steelor in some casesof casehardening steel.
