Thermal distortion compinsation
Thermal distortion compinsation
(OP)
I have a mechanical instrument comprising a polycarbonate frame about 120mm and wheel 100mm dia mounted on miniature ball bearings. I am running into difficulties with thermal distortion causing extra friction on bearings. I am looking for design guides to minimise or compinsate for thermal distortion.
Any help would be apprecisted.

RE: Thermal distortion compinsation
Response if conjecture is correct: Make one half just a cover, but both bearings in the other housing half, so their temperatures track each other and they are naturally aligned. You will probably have to destroy the symmetry of the wheel, too, offsetting the web to clear the bearing housing.
Response if conjecture is not correct: Tell us a little about the problem, already.
