Lignum Vitae as far as I know. Thats why you use it for bearings.

JD, there are several sources of charts etc. that give you the predicted shrinkage of a specie, Holden for example. The one that predictably shrinks the least will also be the one that swells the least. However , the cut of the wood has more to do with it than anything in most cases. Quarter sawn or nearly quartersawn wood with shrink or swell tangently the least in comparison to flatsawn wood. Woods such as Lignum as John mentioned have a heavy oil base such that they do not take up moisture but also provide some self lubrication.
Good Luck on your search.

What the others say.

Eastern White Cedar has a reputation for stability even when flat sawn--one of its many virtues--yet I'm sure it's not the most stable wood in the world.

For cabinet work I learned a rule of thumb for panel work, which was to allow for a quarter inch of movement for foot of width. The movement in the planking of a boat must be considerably more.
