New Designed Double Row Ball Slew Bearing Internal Gear

Double row ball slewing bearing is mainly used for wind turbine electrical equipment and concrete transportation pump trucks. In wind power equipment, the bearing is installed at the root of the propeller to act as a side propeller. The clearance is required to be zero or negative, and the starting friction torque is very large and with high rotation accuracy. In terms of its own characteristics, this bearing has a compact structure, which effectively saves the center diameter of the inner and outer ring mounting holes and improves the load-bearing capacity.

Product Description

Double Row Ball Slewing Bearing（02Series）--Internal 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.
