Therefore, in bottom brackets with external tapered bearings, bearing cages often fail under heavy overloads, and the ball races on the cones of the bottom bracket spindle are frequently damaged as well.

Research by scientists and beekeepers’ experience show that with adequate quality feed and careful management, flying honey producers tolerate wintering well even in severe frost. For a weakened bee colony in cold weather, the trouble is less the low temperature than high humidity, when frames and the inner surfaces of hives grow mold, and the Read more…
