Description
Double-Row Ball Slewing Bearing 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.
Manufacturing facilities and technical abilities
Our inspecting and testing instruments are advanced and
complete, engineers are professional, and management system is
scientific. So we can offer slewing bearings with various types,
specifications, and precision grades.
Quality
