Agriculture

 

Agricultural machinery is characterized by two specifics: non-standard design of bearings and seasonal use. The devices are parked for most of the year, i.e. they are out of service. After that, they are exposed to demanding operating conditions for a short but intense period. And at that time they must serve reliably.

 

The variable mode usually puts more strain on the machines than if they worked in such an extreme deployment continuously throughout the year. As an example, we can mention that they are attacked by corrosion due to atmospheric conditions. It has been proven that corrosion occurs more intensively in conditions where the surface is exposed to continuous wetting and drying than in a situation where the surface is permanently immersed. In operation, parts of agricultural machinery, including bearings, are exposed to variable humidity, dust, variable and in some places also to impact loads or corrosive environments (e.g. when working with fertilizers and other chemicals). Stainless steel bearings are often used in agriculture.
