What types of bearings are used in port lifting machinery?

Lifting and transportation machinery is a multi-action machine that can carry out vertical lifting and horizontal transportation of heavy objects. Mainly including: shore cranes, gantry cranes, ship unloaders, stackers and reclaimers; conveyors, cranes, cranes, and unloaders.

Application type: According to the requirements in the field of lifting machinery, there are many types of bearings that can be used, including: spherical roller bearings, full complement roller cylindrical bearings, tapered roller bearings and slew bearings, etc.

These bearings are mainly used in gear boxes, traveling wheels, cranes, lifting devices, luffing mechanisms and slewing mechanisms of lifting machinery.
