Slewing Ring Bearing

Essential transmission components for machinery which needs a relative rotation and bears axial force, radial force and toppling movements at the same time between two parts of the machinery. They are mainly used for excavators, wind power, tower cranes, truck cranes, crawler cranes, and also widely used in engineering machinery, construction machinery, port machinery, metallurgical machinery, light industry machinery, environmental protection machinery, engineering vehicles, solar energy, wild power, etc.

Slewing bearings are ball or cylindrical roller bearings which can accommodate axial, radial and moment loads acting either singly or in combination and in any direction. They are not mounted on a shaft and in a housing; the rings, which are simply bolted on the seat 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.

The outside diameter range of SKF slewing bearings with a one-piece ring is from 400 to 7 200 mm. Even larger bearings are produced with outside diameters up to 14 000 mm, but these have segmented rings. Some of the smaller sizes, up to approximately 2 000 mm outside diameter are standard production.

Single row slewing ball bearings

SKF single row slewing ball bearings are four-point contact ball bearings. The balls are inserted through a filling slot which is plugged afterwards. The bearings are sealed, have no preload and are intended for applications where demands regarding accuracy are moderate.

Single row slewing roller bearings

single row slewing roller bearings are crossed cylindrical roller bearings. Every second roller is at right angles to its neighbouring rollers. The rollers are inserted through a filling slot which is plugged afterwards. The bearings are under preload and have integral lip seals.

Double row slewing bearings

These slewing rings are angular contact cylindrical roller bearings. The rollers are inserted through filling slots in one of the rings; the slots are plugged afterwards. Plastic separators provide optimum roller guidance. The bearings are normally preloaded and are fitted with integral lip seals.

Triple row slewing bearings

Triple row slewing bearings are combined radial and thrust cylindrical roller bearings for very heavy loads with one one-piece and one two-piece ring. The bearings are not under preload and have integral lip seals. These bearings place high demands on the seat surfaces.
