How important is the wall thickness in the case of plain bearings made of plastic? Can I increase the wall thickness in order to improve stability?

Lars Butenschön | 9. July 2019

In actual fact, what is understood as load capacity mainly depends on the relation of the load-bearing surface to the load to be borne. A plain bearing with a large load-bearing surface can therefore carry more load than one with a small such surface. This means that the inner diameter – namely the shaft diameter […]

Are iglidur plain bearings suitable for use in the food area?

Lars Butenschön | 9. July 2019

Many iglidur materials are compliant with FDA or EU 10/2011 and are therefore suitable for use in contact with food. In the iglidur plain bearing shop, you can use these requirements to filter your search results quickly and easily.In addition, for example,  example, the materials iglidur A181 and A350 can be detected visually due to their special blue […]

What must I bear in mind when I use iglidur plain bearings as rollers?

Lars Butenschön | 9. July 2019

iglidur plain bearings have been optimised for use as fixed-position bearings. This means that the shaft moves in the fixed plain bearing; but it is also possible to fix the shaft in position and design the system so that the bearing moves. You can find further information on this extensive topic in our blog article. Vote […]

Can a shaft be “too smooth”?

Lars Butenschön | 9. July 2019

Yes. Regarding shafts for iglidur plain bearings, we recommend a roughness of 0.2 µm to 0.4 µm. A low degree of roughness can cause stick-slip effects or very fine nicks in the plastic, which can occur as a consequence of high adhesion forces. You can read more about “The right surface finish for shafts” in ourblog article. Vote […]

Are there plain bearings with fire safety certificates?

Lars Butenschön | 9. July 2019

Many iglidur materials fulfil the fire safety requirements according to UL V0 and are self-extinguishing after a short time – for example iglidur GV0. We have developed iglidur RW370 specially for use in railway applications. This material also fulfils the requirements of DIN EN 45545 HL3. – Do you need more detailed information or certificates?
