The counterparts of bearings in a tribological system are important components of the whole bearing system. Their properties directly influence friction, wear, and overall performance. That's why it's crucial to carefully consider the following essential properties – material and precise geometrical properties. We are committed to providing tribologically optimized solutions that maximize efficiency, extend service life, and elevate the performance of the whole bearing systems. We are happy to discuss how your system can be optimized.
To further improve the performance, overall efficiency and service life of bearings, there are various coating options available. These special surface treatments offer benefits such as increased corrosion resistance, improved lubrication, reduced friction and improved wear resistance.
The increase in efficiency is highly dependent on the application and the specific parameters of the system. In many cases, however, plain bearings can lead to considerable increases in efficiency. More precise information can be provided after an analysis of the specific application.

Tribology is the science of wear, friction and lubrication and studies the behavior of interacting surfaces in motion. Tribology is a collaborative, multidisciplinary field involving experts in mechanical engineering, manufacturing, materials science, chemistry, physics and more. It is critical to the optimization of bearing design and lubrication in both natural and man-made systems. Friction is the resistance to movement between bodies in contact with each other. The resulting frictional force can be quantified by the coefficient of friction, which is the ratio between the applied load and the friction. During wear, the irreversible loss of material between interacting surfaces, various physical and chemical mechanisms are at work in the contact area. Friction and wear mechanisms depend on the structure of the tribological system and the induced collective load, which makes quantification and control difficult. To understand tribological theories, the microscopic level of sliding friction and the topography of the surfaces must be taken into account.
