Because of the quieter running properties I have decided for the nylon version. I am (been) very happy with it that I forgive only **** has to do with having to comply, the axle bore any mystical inch- or similar masses, because an M12 bolt as axle does not go through, an M11, there is my do not know. Therefore, the hole had to be extended / drilled, which of course turned out to be time-consuming, since the middle part of a ball bearing naturally turns!
From a sold product in Germany, I expect, if it is otherwise noted that it is also oriented to German standards and opposite characteristics.
