Four Row Cylindrical Roller Bearings
As the most important roll bearing in metallurgical equipment,the four row cylindrical roller bearing has compact structure, high stiffness, and high bearing capacity, which is widely as rolling mill bearing. It is designed to support heavy loads in radial direction, so thrust bearing is suggested to work together for axial loading support.Boundary dimensionsBasic load ratingsDesignationsInstallation dimersionMassmmkNmmdDBFwrminr1minCrCorCurrentOriginaldaminDaminDamaxramaxrbmaxkg.51.1222454FC..51.1222454FC..51.1194416FC..51.1290616FC..51.1335730FC..51.1219457FC.120297020K1501061131.51.1347736FC-6..51.1241602FC-4.FC.FC..5229231610FC-27.FC.FC.FC.FC.FCFC.51.512.FC.51.513.FC.51.515.FC.51.519.FCFC.FC.51.517.FC.51.FC.FC.51.522.FC..12.16901543FC.6324812432K2401681832.12.19472310FC.52.19532326FC-38..5226801720FC.FC.FC.FC.12.110002400FC.9345017034H2601201952.12.18631730FC.2345212034Y2601501952.12.18601948FC..12.110802460FC..12.112703350FC..12.16091583FCFC..52.1693860FC..12.17181668FC.6365212436K2601542022.52.19832200FC..12.18932206FC..12.110602440FC..12.111502560FC..12.112202580FC-43..12.110202600FC..12.18161926FC672822.1385312438K2701242122.12.18161925FC..12.110622798FCK2702002122.12.113593350FC..12.115403350FC-41..12.16151626FC..12.19852670FC..12.111302730FC.12.113603460FC..52.18401975FC..12.113863250FC..12.113003400FC..12.110312814FC..12.113003040FC..12.110853310FC-41..12.111322627FC..12.112833503FC..12.112503070FC..12.113213534FC..52.115993444FC-65..12.111422974FC..12.114703760FC.FC.52..12.113733789FC..12.112193161FC.52..12.116004065FC.52.FC-47.FC.52.570.FCFC-78.FC.FC..12.116203990FC.FC.52.574.FC.52.577.FC.52.591.FC.52.FC.52.595.FC.52.FC.FCFC.FCD-68.FCFC.52.586.2567822056QFC.52.593.FCD.FCDFCD.52.FCD-143.FCDFCFC.52.FCDFCD.52.5134.FC.52.5113.FCD.52.5142.FCD.52.5125.FCD.52.FC.52.FCD.52.5166.FCD.52.5193.FCDPFCDPFCDFC.FCD.FC-128.FCD.52.FCDPFCDPFCDFCDFCDFCDFCDFCDFCDPFCDFCD.FCDFCDPFCDPFCD.FCDFCDPFCDPFCDP×20°2475012200FCDP.FCDP×20°3700018300FCDPFCDPFCDPFCDPFCDPFCDPFCDPFCDPFCDP6728/YFCDFCDPFCDFCDFCD.5×20°5807026000FCDPFCD×20°FCDPFCDPFCDPFCDFCDPFCDPFCDPFCFCDPFCDPFCD6727/662.FCDPFCDPFCDP×20°FCDPFCDP×20°3840023600FCDPFCDP.57.FCDP.57.FCDP.FCDFCD.57.FCDPFCDP×20°FCDP.57.57.FCDP-720911..57.FCDP×20°7.FCDPFCDP.57.57.FCDP.57.FCDPFCDP.57.FCDP.57.FCDPFCD.57.FCDP.57.FCDP.57.FCDP.57.FCDP.57.FCDP.57.FCDP.57.FCDP.57.FCDPFCDP.57.FCDP.57.FCDPFCDP6727/Y×20°7.FCDP×20°7.FCDP.720×20°7.FCDP×20°7.FCDP×20°7.FCDP×20°FCDP.57.FCDP×20°7.FCDP×20°9.FCDP×20°FCDP
