Showdown in the test lab: plastic ball bearings compete against metal bearings in the salt water test2018/11/8
The engineers of the igus test laboratory filled a container with saltwater from the sea and heated it to +80 degrees Celsius. Then two bearings were put inside for 120 hours: a classic 2-hole flange bearing made of metal and a xiros flange bearing made of xirodur B180, a high-performance plastic that has been optimised by igus for years in terms of wear and media resistance. Both bearings were not completely covered in the test, but exposed to air in order to trigger the corrosion effect. |
