When do you use a xiros polymer ball bearing instead of an iglidur polymer plain bearing?

Martina Kölsch | 2. July 2019

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 […]

When I measure the plain bearings, I find them to be considerably larger than indicated in the catalogue. Why is this?

Lars Butenschön | 2. July 2019

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 […]

Which factors influence the wear of a plain bearing?

Lars Butenschön | 2. July 2019

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 […]

Is the colour of the bearing freely selectable?

Lars Butenschön | 2. July 2019

Unfortunately no – the colour is usually due to the composition of the respective material and there are often only a few individual dyes that are simultaneously suitable for a material and do not have an adverse effect on its tribological properties. The wear behaviour depends on the composition of the material (the dye being […]

How is a pin-gauge measurement carried out?

Lars Butenschön | 2. July 2019

1.1 igus carries out a pin-gauge test, also called a “go/no-go test”, in order to ensure that our bearings meet the specifications and function properly once installed. First of all, the bearings are press-fitted in a test housing. It must be ensured that the bearings are undamaged when they are fitted. A housing chamfer is […]
