The diagrams display a summary of the results of tests with different shaft materials conducted with bushings made of iglide® H370.
For loads up to 290 psi, the hard-chromed shaft is the best counter partner for the iglidur® H370 plastic bushings in rotating applications. The high wear values for 303 Stainless shafts, which have a tendency to stick-slip because of their very smooth surfaces. The HR Carbon Steel shaft has better rotational values than Cold Rolled Steel starting at 290 psi.
On the other hand, for oscillating movements, the 303 Stainless Steel shaft has a clear superiority. As the diagram shows, it generates, at 290 psi, a lower wear by the factor of 11 than the Cold Rolled Steel shaft.
