I have designed a small rotating assembly that runs at only 0 - 150 RPM with
very very minimal load, it has a Stainless Steel (303) 3.0mm Dia shaft and a
brass (CZ121) bearing. When first assembled this it has a very smooth
running action and very little stiction, but after a few days of use the
bearings begin to squeek and seize.
Can anyone tell me if there any problems with stainless and brass as a
bearing assembly or point me in the right direction for information on
suitable material pairs for bearings.
