Cross cylindrical roller slewing bearings main structural characteristics: 1:1 cross arrangement of cylindrical rollers.The bearing with this structure features high stability, high precision, and high impact resistance. For example, the cannon's rotary base uses this kind of bearing.


Slewing bearings are large size bearings which can carry higher axial, radial laods and overturning moments at the same time, Slewing bearing generally have mounting holes, internal or external gears, lubricant holes and sealign equipment.


Slewing bearings are widely used in cranes, excavation machines, construction machinery, port cargo handling machinery, large turnplates of high precision radars and missile launchers, etc.
