Bearing selection criteria. Preselection

We distinguish between :

• the vacuum ;

• gas environment: lubrication prohibited or lubrication permitted, with low, normal and high temperatures for each case;

• liquid atmosphere without surface lubricating properties, e.g. water or petrol;

• the crankcase environment forms an oil reservoir, allowing all forms of lubrication - splash, oil bath or pressure - to be carried out without complication;

• the purpose-built housing bearing.

For greater clarity, we'll refer to these moods by the following numbers.
