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 […]
Both iglidur J and iglidur W300 belong to the most wear-resistant all-round bearings in the iglidur product range. If the service life is comparable and sufficient in both cases, the boundary parameters of the application should be decisive for the choice of material: iglidur J is predestined for wet areas due to its low moisture […]
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 […]
