Double Row Ball Slewing Bearing 021.30.1000.002
The 021.30.1000.002 bearing is a Double row ball slewing bearing with an inner diameter of 1142 mm , an outer diameter of 858 mm, a width of 124 mm. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
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 mdeium diameter tower cranes, truck mounted cranes etc. loading and unloading machinery.
Double row ball slewing bearing has three seat ring, he steel ball and the spacing block can be directly arange 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 degree, which can bear large axial forces and tilting moment. Whe the radial force is greater than 0.1 times the axial force need to be specially designed the raceway.
