Our factory is a specialized
manufacturer in slewing
rings/bearings. The double-row ball slewing
ring bearing has three seat-
rings. The steel balls and the
spacers may be directly
arranged into the upper and
lower races. Two rows of steel
balls with different diameters
are fitted according to the
force. Such open mode fitting
features extraordinary
convenience. The load angels
of both upper and lower races
are 90° which enable the
bearing to bear large axial force
and the tipping moment. When
the radial force is larger than
1/10 of the axial force the
races should be newly
designed. As the axle and the
dimension of the double-row
ball slewing bearing are rather
large, the bearing construction
is solidity; hence it is especially
suitable for tower cranes which
require working radius over
medium range, mobile cranes
and loading and unloading
machines.
