Bought a few on Amazon to save a few bucks... not worth it... ended up ditching them and buying these after some came in a Linear Rail kit... Replaced all of the others with these, all of the rails move much more smoothly...
Overall quality is great! Solid machined block , not injection molded. Accepts almost any type of lube, quiet operation. Downside, there super tight! One block of the pair I ordered is tighter than the other. They’re so tight my 2 amp nema 17 motors can turn the lead screw. I have tried a handful of different lubes and ran them back and fourth with a high speed drill. They’ve broke a bit but are still very tight. I drill them out today by 0.080” and they seem to be significantly better. Next step is try them again, fingers crossed it’s enough.
