Single row contact ball bearings

...accommodate axial forces in one direction as well as radial forces. They are usually installed in pairs and pre-tensioned – as tandem, O or X versions. Depending on the design, the forces that can be absorbed axially are changed. Due to the roller guide inclination, a considerable (inner) axial force will be generated even if running under radial load only.

Four point contact ball bearings

... are single-row contact ball bearings that can absorb axial forces in both directions. They therefore require less installation space than two row contact ball bearings.

Two row contact ball bearings

... are principally constructed similar to two single row contact ball bearings installed as an O arrangement. But the design width is narrower than with two single bearings. Radial as well as axial loads can be absorbed in two directions.

Compact bearing units

... are designed like two row contact ball bearings, but have a split inner ring. This is a wheel bearing ready to be installed for e.g. passenger car trailers that are sealed, featuring life-time lubrication. The great advantage of this type of wheel bearing is that no extensive bearing play adjustment is required.

Use of contact ball bearings

E.g. in tools and (light) machine engineering wherever spindle bearings are required.
