crossed cylindrical roller slewing ring

The crossed cylindrical roller slewing ring has relatively higher static capacity. The crossed tapered roller slewing bearing have heavier rigidity and higher running accuracy because of its pre-interference.

It widely used in elevating machinery, harbor machinery, mining machinery, constructional engineering machinery, missile launcher and other large-sized rotators. slewing bearings are extensively applied in such industries as metallurgy, vessel, oil, chemistry, mine, coal, hydroelectric power, port machinery, heavy machinery and aerospace or some other fields.
