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 […]
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 […]
In general, it can be said that xiros polymer ball bearings are preferable to iglidur plain bearings where rotating movements with velocities above 1.5 metres/second can occur continuously with low loads. The significantly lower coefficient of friction of the polymer ball bearings compared to plain bearings ensures less heat generation and lower wear. Decisive is […]
Our plain bearings are press-fit bearings for housings with a standard H7 hole. This press-fitting of the bearings fixes the bearings in place in the housing, and the final inner diameter of the plain bearings is not arrived at until the bearing has been press-fitted.The bearing size is checked when the bearing has been mounted […]
1: Wear test with oscillating motion of an iglidur plastic plain bearing from igus. _x000D__x000D_ Influencing factors: Selection of the shaft: Different shaft materials are recommended for different plain bearings. Each shaft-bearing combination has different wear results. Load: With increasing radial loads or surface pressures, the wear of the plain bearings also increases. Some plain […]
