Three-row cylindrical roller slewing bearings Performance


ZYS three row roller slewing bearings have the following features: High load;Different loads are supported by different raceways and cylindrical rollers separately. Therefore, 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.
