Double-row ball

Double-row ball slewing bearings are composed of up and down double-row rolling balls, inner and outer rolling rings, sliders, lubricating channels and sealing.
Attachment screws connect the upper and bottom rolling rings.

Double-row ball slewing bearings can accommodate combined loads including axial loads, radial loads and lifting moments because of the up and down double-row rolling balls, and the structure is firm.

They are especially suitable for tower cranes which require working radius over medium range, mobile cranes and loading and unloading machines.
Double-row ball slewing bearings can be divided into 3 types:

series-02 with outer gear

series-02 without gear

series-02 with internal gear
