Single bearings and bearing sets

Single bearings

Single, super-precision angular contact ball bearings are available as standalone bearings or as universally matchable bearings. When ordering single bearings, indicate the number of individual bearings required.
Standalone bearings
Standalone bearings are intended for arrangements where only one bearing is used in each bearing position. Although the widths of the bearing rings are made to very tight tolerances, these bearings are not suitable for mounting immediately adjacent to each other.
Single, universally matchable bearings

Universally matchable bearings are specifically manufactured so that when mounted in random order, but immediately adjacent to each other, preload within a predetermined range and effective load sharing will result without the use of shims or similar devices.

Single, universally matchable bearings are available in different preload classes and are identified by the designation suffix G.

Bearing sets

Sets of super-precision angular contact ball bearings are available as matched bearing sets or as sets of universally matchable bearings. When ordering bearing sets, indicate the number of bearing sets required (the number of individual bearings per set is specified in the designation).
Matched bearing sets

Bearings can be supplied as a complete bearing set consisting of two, three or more bearings. The bearings are matched to each other during production so that when mounted immediately adjacent to each other, in the specified order, preload within a predetermined range and effective load sharing will result without the use of shims or similar devices.

The bore and outside diameters of these bearings are matched to within a maximum of one-third of the permitted diameter tolerance, to provide better load distribution than single universally matchable bearings.

Matched bearing sets are available in different preload classes.

Sets of universally matchable bearings

Bearings in these sets can be mounted in random order for any desired bearing arrangement. The bore and outside diameters of a set of universally matchable bearings are matched to within a maximum of one-third of the permitted diameter tolerance, resulting in better load sharing, when mounted, than single universally matchable bearings.

Sets of universally matchable bearings are available in different preload classes.

Like single, universally matchable bearings, sets of universally matchable bearings are identified by the designation suffix G, but the position of the letter G in the designation is different.

Sets of universally matchable bearings are not available in the S70 .. W series.
