The product arrived fine. The pieces fit together perfectly. The measurements are perfectly correct. The BF/BK12 bearings fit properly without excessive force to fit. As for linearity measurements, it was not yet possible to verify if the ball screw bars are well aligned without bending or if they are well centered. The ball screw nut appears to rotate properly and with no perceived play. It comes well lubricated. The very beautiful stainless steel ball screw looks well polished and shiny. The supplier on one of the occasions served me well, answering my questions. The products were not taxed by customs in Brazil, being allowed up to 50 USD.
