Backing Bearings
Backing bearing is a special cylindrical roller bearing. A number of support rollers are mounted on bearing. Each backing bearing's outer surface is used as part of the rolling surface. This would require backing bearing have a uniform cross-section. The accuracy requirements for spare parts are very strict.Boundary dimensionsBasic load ratingsMassStructureDesignationsmmkNkgdDBCCross sectionCrCorH70160.02909044..5114HG329090220.HG449490220.HG449690220..2218HG449490220.HG4412090220.0212012065..5—18HG44120Z90220..6—18HG44120Z.HG45120X.HG45120X.HG45120X.5735138027.7120HG45120X.9222HG5298130300.0213012985..9226HG.0213212985..5226HG.HG.02161.5160..9226HG.02172.65171..3226HG.02172.65171.685..5226HG60172X130300.02172.64172.684..8126HG60172X2130300159..1126HG.4171.04170113.HG.4224220113.HG..HG..HG..HG81224X.HG104168
