Three Row Roller Slewing Bearings
Three-row cylindrical roller slewing bearings PerformanceZYS three row roller slewing bearings have the following features: High load;Different loads are supported by different raceways and cylindrical rollers separately. Therefore,Website:, under same loads, roller diameter can be reduced much more to make the mainframe more compact.Applications: Hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering and etc. Three types of three row roller slewing bearings:A. Without gear bearing (non tooth)B. External gear bearing (external tooth)C.
