Double-row ball slewing bearing 02——External gear
Double row ball slewing bearing (TYPE 1)
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 differently 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.
The axial and radial size of double row ball slewing bearing are relatively large and solid in structure, so it is special suitable for the medium diameter tower cranes, truck mounted cranes etc. loading and unloading machinery.
Double row ball slewing bearing (TYPE 2)
Double row ball slewing bearing has two row rolling balls (with same size), which can bear big axial load, radial load and tilting moment. Safety factor is higher.
It can apply for different cranes, mining equipment, excavators etc.
