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.
Double-row angular contact ball bearings can support axial loads in both directions and high radial loads. They are particularly suitable for bearing arrangements in which rigid axial guidance is required.

DEEP GROOVE BALL BEARINGS
FOUR POINT CONTACT BALL BEARINGS
FAG deep groove ball bearings are available in radial and axial designs for many different variants.
Single-row deep groove ball bearings are available in open and sealed designs. They are designed for high to very high speeds and can accommodate radial as well as axial forces.
Double-row deep groove ball bearings correspond with single-row deep groove ball bearings in design and are used when the radial load capacity of single-row deep groove ball bearings is insufficient.
FAG axial deep groove ball bearings are available in single or double-direction design variants. These bearings are especially well suited to high axial loads.
Four-point contact bearings are single-row angular contact ball bearings and therefore require significantly less space in an axial direction than double-row designs.
The bearings comprise solid outer rings, split inner rings and ball and cage assemblies with brass or polyamide cages. The two-piece inner rings enable a large complement of balls to be accommodated. The inner ring halves are matched to the particular bearing and must not be interchanged with those of other bearings of the same size. The outer ring with the ball and cage assembly can be mounted separately from the two inner ring halves.
Self-aligning ball bearings are double row, self-retaining units comprising outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed designs.
SELF-ALIGNING BALL BEARINGS
Spindle bearings are single-row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed designs.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and suitability for high speeds. They have proven ideal for spindle bearing arrangements in machine tools.
Thin-section bearings are high-precision products with very little running noise and a high load-carrying capacity. These bearings are available in three different designs with extremely small, predominantly square cross-sections. Within each series, the cross-section remains constant even in the case of larger shaft and housing bore diameters. The bearings are therefore also described as constant section (CS) bearings. This feature distinguishes thin section bearings from the conventional bearings that are described in standardized ISO series.
