Large diameter slewing rings are no problem to QCB whose slewing rings already provide reliable service across the globe in construction and mining equipment, and jib cranes (onshore and offshore). 

QCB can supply slewing rings up to 11 000mm in diameter, segmented for easy transport and assembly on site.

Slewing rings with extra large diameters are also in our production range. So far, our large diameter slewing bearings have been used in construction, mining equipment and jib cranes all over the world.

Honza Bearing can provide slewing bearings up to 11,000mm in length, and the segmented slewing bearings are more convenient for transportation and on-site assembly.
