A wheel bearing?
The original thread is on a gimbaled bearing meant to take side loads, not
vertical. The gimbal allows for a change in shaft angle such as in landing
gear of other parts subject to extreme flexing. Much smaller versions are
used in the control linkage to light aircraft control surfaces. They are
also in the ends of the throttle, mixture, and prop controls.
A block of hard wood soaked in a low viscosity oil, cut in two, bolted back
together and then drilled for the mast size will make a bearing that will
last longer than most hams. However the mast surface should be smooth where
it fits in the bearing or it'll act like sand paper. (The oil soaking comes
*after* the fabrication. <:-)) )
