02--Double Row Ball Slewing Bearing----Non Gear
Characteristic of structure,
performance and application
Double
row ball slewing bearing has three seat ring, the steel ball and the spacing
block can be directly arrange into the upper and lower races, two rows of upper
and lower steel balls with different diameter are fitted according to the
stress condition.
This kind of open assembly is very convenient, for the upper and lower bear
raceway arc angles is 90°,which can bear large axial forces and tilting moment.
When the radial force is greater than 0.1 times the axial force need to be
specially designed the raceway.
Double row different ball slewing bearing’s axial and radial size are
relatively large and solid in structure, so it is specially suitable for the
medium diameter tower cranes, truck mounted cranes etc. loading and unloading
machinery.

n1 is the number of lubricating holes. Oil cup M10×1JB/T7940.1~JB/T7940.2. The
Oil nipple's location can be changed according to the user's application.
2. n-φ can changed to tapped hole, the diameter of tapped hole is M,depth is
2M.
3. The tangential tooth force in the form is the maximum tooth force, the
nominal tangential tooth force is 1/2 of the max one.
