Bearing Troubles.

Correct lubrication may be regarded to-day as a science. Just as the chemist knows what results will follow the mixing of two substances under known conditions, so the fully-informed lubrication engineer can foretell what results will be the effect of applying a given lubricant to a bearing subjected to known mechanical and operating conditions.

Incorrect analysis of the factors influencing lubrication, failure to observe the true conditions, and lack of knowledge of the correct lubricants, necessarily lead to incorrect lubrication; and the penalties are troubles, wear and repairs, page 43 depreciation of equipment, and the expense of replacement. This negative aspect of lubrication calls for discussion, in order that incorrect conditions may be rectified.
