Triple Row Roller Slewing Rings
Used for very heavy loads and available in either geared or ungeared forms up to 8500mm diameter.
Roth Erde and RKS catalogue a few basic sizes, but most are specially designed for a specific application and therefore often not catalogued.
All bearings manufactured by NBC are delivered with material certification and a factory dimension report, but for offshore applications that require Lloyd's or DNV Approval we are able to offer full traceability from forge to finished product as well as the required design calculation file.

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. winches and cranes)
