Wearout Analysis of Bearing Shells

Bearing shells have the function of rolling and supporting rolling elements. In four-stroke engines, for example, the connecting rod that connects the piston to the crankshaft rotates in a bearing. This is lubricated with oil, which reduces friction and thus wear. However, the lubricant contains various residual contaminant particles that can become lodged in the bearing shell.

How Pure is Distilled Water?

Distilled water has many uses in everyday life, for example as coolant in cars or in steam irons. It has the reputation of being purer than tap water, which is why distilled water is also used for cleanliness analysis in the laboratory. Residues in the water would contaminate the samples during analysis and distort the results.
