US Patent 7552542 Measuring arrangement and measuring method for measuring bearing clearance

A measuring arrangement for measuring clearance between a bearing internal part and a bearing external part of a bearing, in particular in an aircraft or spacecraft, is disclosed. The idea underlying the measuring arrangement is to adjust the bearing part relative to the bearing external part with an adjusting device and to measure the adjustment carried out with a measuring device. The advantage according to the measuring arrangement is that a much more accurate and repeatable measuring may be achieved relative to current measuring which depends on the intuition and experience of the mechanic.
