Slewing bearing different structure, different advantages

Single row/double row Ball Slew Ring Bearings
The single-row four-point contact ball slewing bearing is composed of two seat rings.
Designed for average axial forces and tilting moments as well as high radial forces
Compared with the single-row version, the double row bearing can support higher loads at the same diameter
Applications: Mechanical engineering, construction equipment, wind turbines and ship loading/unloading applications

Double-Axial Ball Slew Ring Bearing
Simple and robust design with sufficient clearance
When tilting moments quickly change their amount and location
Where the slewing ring is subjected quick and continuous load changes
Applications: Open pit mining machinery like bucket-wheel excavators

Three-Row Roller Slew Ring Bearing
Used in highly demanding conditions
High static and dynamic load-carrying capacities
Applications: Rolling mill equipment, heavy-duty cranes and tunnel boring machines, mining machineries, etc,


Cross-Roller Slew Ring Bearing
Used to support high radial forces as well as average axial forces and tilting moment loads
Zero clearance and uniform bearing friction
Applications: Mechanical and plant engineering, medical device and antenna equipment

Combi Slew Ring Bearing
Used in conditions of high axial forces and relatively low tilting moment loads
Applications: Bulk handling and conveyance equipmen
