After 2560 test kilometres with carbon fibre shafts it is definite: iglidur® J260 is best suited for carbon fibre shafts

Wherever masses are moved, it is becoming increasingly important to use lightweight and stable materials in order to save weight, energy and money.

Carbon fibre shafts were tested in conjunction with various iglidur® bearings. The wear rates determined for the individual materials were very different - and in some cases surprising, even for the material experts at igus®. Not every iglidur® material that is one of the best performers on metal shafts also performs well on carbon fibre shafts.

The combination of carbon fibre shafts and plastic plain bearings may sound too special and incompatible at first. However, carbon fibre shafts are becoming increasingly interesting for numerous areas of application due to their material properties. They are characterised above all by their low weight combined with high flexural strength.

25 different high-performance polymers were tested in combination with carbon fibre shafts to find out which combination is the best in terms of coefficient of wear. A total distance of 2560 kilometres was covered on a test rig for linear short-stroke.

Here are some details from the test:

• Radial load on the bearing: 1 MPa
• Speed of the shaft during linear movement: 0.1 m/s
• Temperature: 23°C
