Slewing bearings are ball or cylindrical roller bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction.

They are not mounted on a shaft or in a housing; the rings, which are simply bolted on the seating surface are available in one of three executions:

• Without gears
• With an internal gear
• With an external gear

Slewing bearings can perform both oscillating (slewing) movements as well as rotating movements.

Triple Roller Slewing Bearing

Characteristic of structure, performance and application.

Triple roller slewing bearing has three rings, which separate the upper, lower and radial races, via which the load of each row of the rollers may be specified. It can carry different loads simultaneously and its load capacity is the largest one among the four models.

Thanks to the large size of its axle and radius, it is sturdy and especially suitable for heavy-duty machines which require large working radius. such as bucket-wheel excavators, wheeled cranes, ship cranes, ladle turret, heavy-duty mobile cranes etc.
