I was perusing for a specific bearing and came across this website. They have a CAD download section which includes "Alibre Design >V11". I didn't go too deep but they have rolling and linear products. I tried a couple of examples and yes, they import into AD (2017.1.2) just fine. The feature name is "STEP Importe". Just thought I'd share this for anyone looking for bearings. I did try to edit the parts but they won't change color. I didn't try to change anything else but the "measurement tool" works. Redraw, anyone" http://medias.schaeffler.com/medias/en!hp/ Also in various languages.
