The graphs show a summary of the results of tests with different shaft materials conducted with plastic bushings made of iglide® P.
In rotating applications, the wear of iglide® P is very low with Cold Rolled Steel and HR Carbon Steel shafts. On the other hand, the bushings on 303 Stainless Steel shafts as well as hard-chromed shafts result in higher wear than other shaft materials even in the lowload range. For example, at a load of 290 psi Cold Rolled Steel is six times better than 303 Stainless Steel.
The wear rates of low-stressed bushings in pivoting motions with most shaft materials are lower than in rotating applications. For this purpose, the Cold Rolled Steel and hard-chromed shafts prove to be the best sliding partners. Also, the 303 Stainless Steel shafts that have poor results for rotation, are excellent for the oscillating application.
