    O kit tem ótima qualidade, o parafuso, o noz, os rolamentos e o acoplador tem excelente qualidade e encaixe. Vale a pena. Faltou apenas a chave para apertar os parafusos.

    The pitch is 2 mm and the lead screw has 4 starts, so one revolution equals 8 mm travel. The description did not give the starts. It's good for me because with steppers that 0.9 per step, I get 0.02 mm every step and with 1/4 micro stepping it gets down to 0.005 mm. I don't think I get that accurate but it's a nice idea. The lead screw comes in a hard plastic tube that protects it very well from bending in transport. I'm pleased!

    I recently ordered 2 of this for a DIY CNC project that I'm working on, one of them already arrived, the second one will arrive today, in general the product feel and looks great with some minor QC details due to the fabrication and assembly process, but in general it's more than OK. The lead Screw is well packet and protected, so it's not risk of bending problem during the shipment process, good for them. The Nut and the Shaft Coupling was machinery well, so in overall the products are very good so far, later on I will test these with my project and publish the results here. The only issue was that one of the Mounted Ball Bearing became without the screws that hold align and in place the Lead Screw, I'm pretty sure that the seller will fix that issue.

    Неплохой полный комплект для установки. Из минусов только могу отметить паршивую гайку с люфтом порядка мм.
