Hanged Ball Bearings
There are many advantages in using miniature and instrument ball bearings which have a flange on the outer ring. Stepped housing bores, which make it impossible or very difficult to maintain accurate alignment of both bearing fits, are not necessary. There is also no need for the use of circlips, which create difficulties in small housing bores or thin walled housings (Fig. 7).

Furthermore the assembly of flanged bearings in relatively narrow housings (i.e. gearboxes) has proved effective (Fig. 8).
If duplex bearings are used, the use of a flanged bearing simplifies the design of the locating bearing. The axial position of the Duplex bearing pair can be determined precisely for this arrangement (Fig. 9).

Ball Bearings with Extended Inner Rings
Ball bearings with an extended inner ring can simplify the design of various assemblies. Shims, washers and other spacers are unnecessary. Stepped shafts are also redundant (Fig. 10).

Ball Bearings with Reinforced Outer Rings
Ball bearings with their outer rings supported by a fitting in the housing can take the highest loads. To increase the load capacity of ball bearings which are not built into housings different types such as “special ball bearings with reinforced outer rings” were developed and are used as so-called rollers (Fig. 11).
