Wear examination of igubal® pillow block bearing

A customer is constructing a solar energy system, where its moving solar panels follow the sun. To identify a suitable pillow block bearing for the pivoting movement of bearing points, the application was reproduced on the universal test bench in the igus® test laboratory.
 
The goal of the test series was to determine for the customer the most wear-resistant pairing of shaft and iglidur® material.
 
The test was carried out under the following test parameters:

Conclusion:

With a wear rate of 30.88 µm/km the pairing of iglidur® J4 with a shaft made of galvanised steel is the solution with the least wear. It should be mentioned that there was hardly any wear on the galvanised surface of the shaft. The spherical balls made of iglidur® J4 is very gentle on the shaft, whereby the rust protection is maintained for a long time.
