Three Row Roller slewing 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 slewing bearings are excellent solutions in applications where a high degree of stiffness is necessary, however they require rigid and precise mounting structures.

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.
