When you say the BB is loose, are you referring to the cups or the axle itself? If it's the cups, just tighten them. Unless you have an Italian threaded BB, which could explain the loosening cups. If it is an Italian threaded BB and it doesn't already have some form of thread prep(which UN-26's don't) then it requires locktite on the non drive side to help keep it from working itself loose.

If it's an english thread BB and the cups are continually coming loose then it's either been installed improperly or your cups need to be faced badly. When you go to swap your BB don't forget that english thread bottom brackets are threaded opposite of pedals. So drive side is left hand, non drive is right hand. Italian thread are Right hand on both sides.
