Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet metal or brass cages. The raceways of the inner and outer rings are offset from each other along the bearing axis. The bearings are available in open and sealed designs. Their angular adjustment facility is very limited.

Radial and axial load capacity:
Single row angular contact ball bearings can support axial forces in one direction and high radial forces. They must be axially adjusted against a second bearing fitted in a mirror image arrangement.
The axial load carrying capacity is dependent on the contact angle; i.e. the larger the angle, the higher the load to which the bearing can be subjected. Due to the contact angle of 40°, these bearings can support high axial loads.

Universal design:
Single row angular contact ball bearings of universal design have thesuffix UA, UL or UO and are intended for fitting in pairs in an X, O or tandem arrangement or fitting in groups. These bearings can be fitted in any arrangement required.
The suffix UA indicates small axial internal clearance, the suffix ULindicates slight preload and the suffix UO indicates freedom from clearance in an X or O arrangement.
When ordering bearings, the total quantity of bearings must be stated, not the number of bearing pairs or bearing groups.

Matched bearings:
Sets without an intermediate ring are available in an O arrangement (DB), X arrangement (DF) or tandem arrangement (DT).
When ordering bearings, the number of sets must be stated, not the number of single bearings.

Sealing:
Bearings with the suffix 2RS have lip seals on both sides. Contact RS seals  are suitable for giving protection against dust, contamination and damp atmospheres.

Lubrication: 
Bearings with lip seals on both sides are greased with a high quality grease and are lubricated for life.
Open bearings and bearings with seals on one side are not greased. They can be lubricated with grease or oil.

Operating temperature:
Open angular contact ball bearings can be used at operating temperatures from –30 °C to +150 °C. Bearings with a diameterD ＞ 240 mm are dimensionally stable up to +200 °C.

Cage:
Angular contact ball bearings with solid cages made from glass fibre reinforced polyamide have the suffix TVP or TVH.
Solid brass cages have the suffix MP.
The bearings are also available with universally applicable sheet steel window cages (suffix JP).
