Choose the right shaft material

The right choice of shaft and plain bearing plays a crucial role in a well-functioning bearing system. Plain bearings protect the drive shafts and components surrounding the bearing point from wear. These components are often much more expensive, so it is very important that this wear occurs only in the plain bearing, which must be replaced in good time. But the shaft is often neglected during bearing point design. Find out how to properly harmonise the two components.

Installation and tolerances

During plain bearing installation, there are a few things to consider that are crucial for error-free function and service life. Find out everything about suitable installation and test methods, clearance specifications, standard tolerances, and the correct way to secure plain bearings.

What is tested and how?

In the iglidur test area, bearings and materials are tested for stress, wear, and friction properties. Other parameters such as high and low temperatures, high loads, and speed are adjusted as the test requires. There are around 50 test systems in the test laboratory, where more than 300 tests are carried out at the same time. We also perform around 11,300 tribological tests on around 250 newly developed plastic compounds every year. To ensure that the new formulations are effective in later use, they are exposed not only to external influences, but also to different movement directions and loads: rotating, pivoting, linear motion, and tumbling.
