Calculating surface speed at bearing points

Lars Butenschön | 24. June 2021

To correctly design plain bearings, you primarily need two fundamental parameters: the sliding speed (v in metres per second) and the load to be carried (p in N/mm²). Together, they give you the pv value, which is an important quantity in the selection of plain bearings. Calculating the load or surface pressure is relatively simple, […]

Comparison of plain bearing materials: bronze bushings and other alloys

Lars Butenschön | 14. May 2021

Bronze bushings, like many other purely metallic bushings, are based on a so-called alloy. In this process, metallic “mixtures” are created by melting together different types of metal, which in turn have different specifications. A direct comparison of these different alloys with the no less numerous different polymer compounds, which are common in polymer bearings, […]

Plain bearing materials in comparison: metal-polymer plain bearings

Lars Butenschön | 6. May 2021

In this section of our series of articles on the subject of plain bearing materials, we look at the so-called metal-polymer plain bearings. What are metal-polymer plain bearings? How do they differentiate themselves from other types of bearings? What are they particularly good for and when is it better to leave them alone? In this […]

Comparison of sintered bushings: advantages and disadvantages

Lars Butenschön | 18. February 2021

Sintered bushings or plain bearings made of sintered bronze are used in many bearing applications. They are comparatively cheap to procure, available in many dimensions and are sold as “self-lubricating” or “maintenance-free”. However, sintered bushings are by no means as universally applicable as many users think. In this blog post, I will take a closer […]

Polymer coating – the way to protect parts from wear and tear

Lars Butenschön | 5. February 2021

Surface coatings have long since established themselves in all areas of everyday life. From frying pans to bicycle frames, the range of different coating materials and their properties is huge. A more recent phenomenon is the so-called tribological polymer coating. These are plastic-based coatings that have been additionally improved tribologically – i.e. for use as […]
