Description

It is comprised of double row steel balls in upper and lower layers, inner ring and outer ring, spacer, lubricating and seal fittings. The inner ring and outer ring are in two separate structures and two half rings need to be fixed by joint bolts. Due to the upper and lower rows of steel balls, the bearing can carry radial force, axial force and tilting moment simultaneously. Mostly, the bearing is working under axial force and tilting moment together. The axial&radial size of this kind of Slewing Ring all are rather big and the structure is firm, so it is especially suitable for some Loading&Unloading Machines of over-medium diameter, such as, Tower Crane, Truck crane, and so on.
