|Single Row Four Point Contact Ball Slewing Bearing......( 01/HS/Q
Single Row Four Point Contact Ball Slewing Bearing
is composed of 2 seat rings.It features compact in
design, and light in weight.The balls contact with
the circular race at four points,via which the axial
force,radial force and resultant moment may be
It can be used for slewing conveyer, welding
manipulator, light & medium duty crane,
excavator, and other construction machinery,
welding arms and positioners, light,medium
duty cranes,excavators and other
|Single Row Crossed Roller Slewing Bearing...... ( 11/HJ series )|
The Single Row Crossed Roller Slewing Bearing is
composed of two seat-rings. It features compact
in design, light in weight,high precision and small
fitting clearance. As the rollers are 1:1cross
arranged,it is suitable for high precision mounting
and capable to bear axial force,resultant moment
and considerable large radial force.
The single-row crossed roller Slewing Bearings
are widely used for hoisting,transporting,
engineering machines as well as for military
|Double Row Ball Slewing Bearings ...... ( 02 series )|
The Double Row Ball Slewing 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 bom. Such open mode fitting
features extraordinary convenience.The load angles
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 sturdy ,hence it is
especially suitable for tower cranes which
require working radius over medium range,
mobile cranes and loading and unloading
|Three Row Roller Slewing Bearings...... ( 13 series )|
The Three Row Roller Slewing Bearing has three
seat-rings, which separate the upper,lower and
radial races,via which the load of each row of the
rollers may be specified.It may bear different loads
simultaneously and its load capacity is the largest
one among the four models.
Thanks to the large size of its axle and
radius, it is sturdy and especially suitable
for heavy-duty machines which require large
working radius, such as bucket-wheel
excavators, wheeled cranes, ship cranes,
ladle turrets, heavy duty mobile cranes etc.
|Light Type Slewing Bearings ...... ( 06/23 )|
The light type (thin section) slewing bearing has
the dame structure with the ordinary slewing
bearing, but the weight is light, and rotate flexibly.
Widely used in the food machinery, canning
machinery and environment machinery, and etc.
