Horizontal Bearings Power Transmission Products - Innovative Industrial Combination Ideaker Review

Bought these for part of a wood milling project. 1 of the bearings came with free parts, oh wait those ball bearings should be in there. Well, good luck figuring out which ones. I tried some method but 1 out of 4 moved erratically - probably one didn't have its "balls". After repeated disassembly, a few more ball bearings fell out. They are incredibly small to fit back in. So I'm ordering replacement bearings now, but everything else seemed fine.

I ordered this 200mm along with a 500mm kit from the same 'manufacturer'. and some ingots made from recycled aluminum cans in the form of rail supports with hex head screws that pop off with very light pressure, then that's what you need. Oh, and one of the pillow bearings was somehow dented at a 20 degree angle. Only the best components. Avoid this junk like the plague.

If you are looking for precision bearings that can handle heavy loads at high speeds, then this set is not for you. And that shouldn't come as a surprise. The price I paid was ridiculously low. I am a mechanical engineer and have purchased many custom rails and linear bearings for my job. I would never buy this for something I'm building at work. At work, I only buy European and Japanese branded products. And they are much more expensive than this kit. I bought this kit for a small home project
