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.
