Basic knowledge

Rolling bearings are robust and reliable components in mechanical engineering and custom machine construction. Under certain conditions, however, bearing damage to these widely used machine elements can occur, usually resulting from unusual behavior during operation. In the worst case, bearing damage can result in a complete failure of the rolling bearings, which can result in unwanted downtime. Therefore, it is important to detect the first signs of rolling bearing damage early on and to remedy their causes. In this article, we discuss the symptoms of bearing damage, its causes and typical failure modes.

Surface roughness and surface hardness are important properties that must be taken into account when selecting components. Although there are different methods for measuring the roughness or coarseness of a component surface, these measurements often have to be converted to a standard measure.

Bearings are an essential component for fixing and guiding rotary and torsion shafts. They can have a major impact on the service life of your system and machines, which is why it is important to make the right choice. This article describes which bearings are best suited for rotary and torsion shafts and what you need to consider when selecting them.
