How is an iglidur plain bearing fixed in place in a bearing housing?

Lars Butenschön | 2. July 2019

The iglidur plain bearings are designed in such a way that they can be press-fitted in a housing with H7 tolerance and the nominal dimensions of the bearing’s outer diameter, and are then fixed in place by means of a press-fit. This is achieved due to so-called interference , in other words the bearing’s outer […]

What makes a self-lubricating polymer plain bearing so special?

Lars Butenschön | 2. July 2019

Some engineers are reluctant to consider plastic bearings in their designs. Perhaps they have become accustomed to metal or bronze bearings for years, or they simply doubt the suitability of plastic for difficult applications or environments. However, plastic bearings can withstand extreme temperatures, enormous loads and high speeds. One has to know the pros and […]

What is meant by the stick-slip effect?

Lars Butenschön | 2. July 2019

The stick-slip effect refers to the jerking motion that occur when two solid bodies slide against each other. This phenomenon occurs when a body is moved whose static friction is significantly greater than the sliding friction. _x000D__x000D_  Imagine a heavy carton that you want to push over a smooth floor. The carton is heavy, which […]

What is the technical core competence of igus concerning plastic bearings?

Lars Butenschön | 2. July 2019

Over the years, the material developers of igus have developed hundreds of material compounds, of which nearly 40 have now found their way into the polymer plain bearing catalogue. The basic structure is usually the same:_x000D_   1. Base polymers that characterise the fundamental tribological, mechanical, thermal and chemical specifications of the bearing 2. Fibres […]

Why do the plain bearings not need any lubrication?

Lars Butenschön | 2. July 2019

Due to the special make-up of the iglidur materials, which are usually composed of a thermoplastic matrix, fibre reinforcements and so-called solid lubricants. The good wear and friction properties of the matrix or base material are additionally enhanced by the solid lubricants. During operation, there are always enough particles of solid lubricant on the surface […]
