Triple Row Roller Slewing Rings
While basic sizes are catalogued by companies such as Roth Erde and RKS, many are specially designed for a specific application. QCB® is currently developing a catalogue for this series concentrating on small diameter units to 5 000mm diameter.
All triple row QCB® bearings are delivered with full material certification and a factory dimension report. Third party inspection by Lloyd's or DNV (or similar) can be arranged if required; and we can ship direct to shipyards in China, Europe, or elsewhere in the world.
Offshoot designs of the three row roller bearing include the Axial Roller Bearing and the Roller/Ball combination bearing, used where there is a smaller degree of eccentricity on the load conditions.
Typical applications include mining and materials handling equipment (e.g. stacker/reclaimers); offshore technology (e.g deck cranes)
