Pairs of universally matchable bearings: CB (normal), G<br />

Availability CA and CC: († matrix 1, page 500)<br />

Values: († table 5, page 488)<br />

Values apply to unmounted bearing sets, arranged back-to-back<br />

or face-to-face under zero measuring load.<br />

Pairs of universally matchable bearings: GA (light preload)<br />

Availability GB and GC: († matrix 1, page 500)<br />

Values: († table 6, page 489)<br />

Values apply to unmounted bearing sets, arranged back-to-back<br />

or face-to-face.<br />

Bearing pairs arranged back-to-back: ≈ 2 minutes of arc<br />

Bearing pairs arranged face-to-face: ≈ 4 minutes of arc<br />

The permissible angular misalignment between the inner and outer rings<br />

depends on the size and internal design of the bearing, the radial internal<br />
