Roller/ball combination slewing bearings PerformanceZYS roller-ball combination slewing bearings can support high axial load and low tilting moments.The roller ball bearings are usually large diameter slewing bearings. This series of slewing bearings is mainly made up of inside and outside rings. Upper-row use rollers anddown-row use balls. Applications: ZYS Roller/ball combination slewing bearings applies to high axial force and continuing working situations. It is application in ladle slewing mechanism.This series of ball and roller combined slewing bearings are applies to high axial force and continuing working situations. It is application in ladle slewing mechanism.Three types:A. Without gear bearing (non tooth)B. External gear bearing (external tooth)C. Internal gear bearing (internal tooth)
