Review on MGN12H Sliding Carriage Printer Machine Power Transmission Products by Lance Harrison

I bought 8 of these. It turns out that all the reviews are correct. There are terrible and wonderful. This is gambling. 2 of them were amazing. 1 fit well, 2 was a little tight, 3 was a little tight. I thought maybe it was a preservative but nothing changed even after cleaning. I could swap and lock too tight and they will always run tight or with any lock on well adjusted rails and they will always fit well. So it's rails, not blocks. I bought these because they had a super deal of $11 and I needed more blocks for the rails that I already had so I decided to buy the blocks for $11 and get the rail for free. A word of warning, in any case these rails and blocks are not intended for use with rails from other manufacturers or black MGN12H labels. Another manufacturer had a notch depth of 9.30mm, while this one was about 8.90mm. Would have given two stars but I bought them at such a bargain price that because I won't return them they are guaranteed 3 stars for the value. I will keep them. In the end it was a good deal for me. Super tight rails I can use for a lead screw axle and the other 5 are great for a belt driven axle. Если вы просто покупаете один или два рельса, это того не стоит, потому что вы можете получить все дрянные, и вы можете купить другие дешевые рельсы от другого производителя, которые могут стоить вдвое дороже, но они все еще дешевы, и вы получите то, What did they want.
