These sets of three matched super-precision angular contact ball bearings are available in a wide selection of designs, variants and arrangements, enabling them to be incorporated into virtually every machine tool application as well as other applications where precision bearings are required. Preconfigured arrangements include: tandem; back-to-back and tandem; face-to-face and tandem. Sets arranged in back-to-back and tandem, or face-to-face and tandem, are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. Sets of three bearings paired in tandem need to be mounted against a single bearing, or another set of bearings in tandem, to achieve a the desired preload. The bore and outside diameters of the 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.

| Basic dynamic load rating The basic dynamic load rating Cr or Ca is the load which a bearing can theoretically endure for a basic rating life of one million revolutions. This is expressed as pure radial (Cr) load for radial bearings and pure axial (Ca) load for thrust bearings |
172 kN |
| Basic static load rating The basic static load rating C0r or C0a is defined as the load that results in a certain value of contact stress at the centre of contact of the most heavily loaded rolling element/raceway. C0r is indicate for radial load-, C0a is indicate for radial load rating. |
172 kN |
| Tolerance class |
P4A/TBT |
| Contact angle The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis |
25° |
| Matched arrangement Angular contact ball bearing can be arrangement in different sets. ----- Back-to-back (O) or Face-to-Face (X) or Tandem (>>) ----- The O- and X-arrangements of two precision angular contact ball bearings makes it possible to take up axial loads in both directions. High axial loads in only one direction are supported by a tandem arrangement. |
