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.
