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 […]
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 […]
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 […]
The variety of iglidur materials is the result of very different customer requirements over almost the last three decades. Development of a good plain bearing material is often like squaring the circle. If an improvement is made in one particular direction, this usually happens at the expense of another property. – Most technical applications can […]
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 […]
