Heavy Load Internal Gear Double Row Ball Slewing Bearing for Tower Crane

5 0 Reviews
A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)

Double row ball slewing ring bearing is widely used in tower crane for slow-turning under heavy load. As the load situation for harbour crane and shipyard crane is relatively larger, Double row ball slewing ring bearing can provide better load performance.

 

In tower crane, slewing ring bearing serves as a joint between the upper structure and the undercarriage, providing a means of 360-degree rotation.

                            

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.

Double row different ball slewing bearing's axial and radial size are  relatively large and solid in structure, so it is specially fpr the medium diameter tower cranes,truck mounted cranes etc.loading and unloading machinery.
