Have you ever seen a plastic ball bearing with races made of two different materials? This two-component ball bearing is intended for applications where high speeds and low noise are required. But what is the advantage?
Polymer bearings have already been used in bicycles for many years and are gaining more and more popularity – whether in pedals, frame bearings or gears. iglidur® materials offer more advantages such as: weight reduction, corrosion resistance and longer service life. In contrast to metallic bearings, the tribo-polymers from igus do not require additional lubrication, […]
When threads are used in heavy-duty applications, they must meet many requirements. One of the most important aspects for heavy loads is the stability of the threads under high axial and radial loads. But does this also work with lead screw nuts made of polymer? Clear answer: Yes! The drylin lead screw technology development team has set itself the task of developing a robust alternative to the flange lead screw nut.
The bicycle is still very popular as a means of transportation. But whether the bike in question is a lifestyle product or a racing machine, the quality challenges for each component are great. Many technical components have profound effects on quality. There are shock absorbers and gear and brake components, of course, but bicycle pedals […]
Wherever food or beverages are processed, filled or packed, contamination can occur. If it is salt or sugar, it is important to take a close look at the abrasive (rubbing/grinding) wear. In this way it can be determined what influence this has on the plain bearing or linear guide. In order to examine such contamination, […]
