Ball Bearings

Angular contact ball bearings are available in single-row and double-row designs. They are predominantly recognisable by raceways in the inner and outer rings that are offset from each other. Angular contact ball bearings are designed for bearing arrangements that support both high radial and high axial loads.If necessary, individual angular contact ball bearings can be installed in pairs: in tandem arrangement (if the load-carrying capacity is insufficient), in O or X arrangement (for combined load carrying).

Self-aligning ball bearings always have two rows of balls that share a common raceway. This type of bearing is used when the bearing arrangement must compensate for misalignments or shaft deflections.

Four-point contact bearings belong to the category of single-row angular contact ball bearings. They absorb both radial and axial forces. It should be noted here that the radial and axial forces acting on the bearing must have a certain ratio, as four-point contact bearings have a split inner ring (standard design QJ). Special four-point contact bearings with a split outer ring (type Q) are rarely used.
