Straight as a die...no damage and fit and finish is all okay
The common concern and repeated comments around small diameter and cheaper priced 'linear motion kits', is that they're always bent, with threadforms distorted and generally useless in there intended application.Well, these are clearly bucking that trend. The kits turned up individually packed, well protected, absolutely straight and with the level of fit and finish I was expecting to achieve. (only after I spent some time tidying them up)So the 3 major concerns I had...would the screw be made of chinesuam of the grade 'cheese?'...No, its, hard, the threadforms are flawless and there's no damage.The bearings. ( I worried they'd be sloppy lose and impossible to align)...not so, they're tight fit to a good tolerance and work as intended.The tapped threads.... this is often a bugbear where a supposedly precise component which relies on mating exactly to a reference plane will turn up with thread torqued out've alignment and unususeable... guess what these are all properly tapped and straight,.People, I have purchased 2 sets of the same kit - 1 @ 500mm and 1 @ 300mm. I can report, that I have received every single piece of 'both' 15pc sets.. all of them are in good condition, fit together and work as intended right from the packet.Pleasantly surprised... result. Will definitely buy again for future iterations of the machine I'm building

Not the best quality sliding fits....
Well Packaged and quick delivery with Prime.....Let down on the actual quality of the running fits. Different amounts of ‘play’ / or looser fits on each of the linear bearing blocks means I might have to look at buying a different set.
