Waring Commercial MX1200XTX Xtreme, Is this normal?

We return our Vitamix 6300 as it shows that same black residue problem in the jar (jar issue). So we purchase the Waring Xtreme MX1200XTX. Surprise we saw more black residue with the Waring jar also (maybe these important parts are made by the same part manufactures?). Is this safe to consume with your drinks? Is this normal for all high-powered blenders? So far Nutrilbullet doesn't have these issues, so probably this due to the bearing assembly? Not sure what cause these to show, but guess we will have to settle for a less powerful blender for now. Maybe 5 yrs later these issue will be solved. Nothing wrong with Vitamix & Waring, its their jars that has this problem.
