Double row ball slewing bearing
FROM:Luoyang precision bearing factory    TIME:2009/6/19    HIT:875

Slewing bearings are ball or cylindrical roller bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction.
They are not mounted on a shaft or in housing; the rings are simply bolted on the seating surface. The four point contact ball bearings are available in one of three executions:
-Without gear
-With internal gear
-With external gear
Slewing bearings can perform both oscillating (slewing) movements as well as rotating movements.
The double row ball slewing bearing has three rings, the ball and the spacers directly arranged into the upper and lower races.
Double row balls with different diameters are fitted according to the forces. The load angles of both upper and lower races are 90,
which enable the bearing to carry large axial forces and tilting moment. When radial force is larger than 1/10 of axial force, the races should be
newly designed. As the axle and the dimension of double row ball slewing bearing are rather large, the bearing construction is sturdy, so it is especially
suitable for tower cranes, mobile cranes and loading and unloading machines, etc.
