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?

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 […]

Can I use materials underwater?

Lars Butenschön | 9. July 2019

All iglidur materials can be used underwater. However, they differ from each other considerably in respect of moisture absorption – and therefore in respect of dimensional change as a consequence of long contact with water – and of wear resistance. For plain bearing applications underwater, we therefore especially recommend iglidur materials with low moisture absorption and good […]

What is the heaviest load to which I can subject iglidur PRT slewing rings?

Lars Butenschön | 9. July 2019

This depends on the size of the slewing ring. The maximum permissible load on the currently largest iglidur PRT, PRT-01-300, is 150 kN statically in an axial direction, which corresponds to a weight of 15 t. During movement, the permissible load is 90 kN. For the smallest model, PRT-02-20 – for applications with small loads and simultaneously high pressure […]

Can I machine iglidur plain bearings?

Lars Butenschön | 9. July 2019

Plastic is easy to process and machine. Simple, conventional devices and machines as used for woodworking and metalworking are usually sufficient for machining purposes. In addition, iglidur plain bearings have a homogeneous structure. This means that you do not have to worry about roughened-up gliding layers or damaged carrier surfaces. In many cases, a changed surface […]
