Bearable means just about possible to put up with. Barely bearable, made it bearable, not bearable.
It sets a low bar and says so: calling something bearable admits it is unpleasant. It is used of pain, weather, company and waiting. Note unbearable, which is much commoner and much stronger; and that bearable comes from bear in the sense of carry, so what is bearable is what can be carried.
