The three row roller slewing bearings have the following features: High load carrying capacity;Different loads are supported by different raceways and cylindrical rollers separately. Therefore, under same loads, ball 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 Row Roller Bearings are constructed with three independent rows of rollers to handle a combination of axial, radial and overturning moment loads. The rollers are oriented for optimum load carrying capability.Three Row Roller bearings are excellent solutions in applications where a high degree of stiffness is necessary, however they require rigid and precise mounting structures.Our Bearings has analysis software that will optimize the configuration and sizing of the rollers to most meet the needs of the application and loading. As with all of our slewing bearings, Three Row Roller Bearings can be supplied with internal or external integral gearing.
