How Water Causes Bearing Failure - Machinery Lubriion

It is not good at bearing high-pressure loads. This results in collapsed film strength followed by fatigue cracks, pits and spalls. Water can also flash or explode into superheated steam in bearing load zones, which can sharply disrupt oil films and potentially fracture surfaces.

6 Most Popular Types of Mechanical Bearings - Craftech Industries - High …

A mechanical bearing is a component used between two parts that allows rotational or liner movement, reducing friction and enhancing performance to save energy. Both metal and plastic bearings can be found everywhere, from refrigerators to computers to the 100 or so bearings found in your car. The concept behind them is a simple one: things roll better than they slide. …
