Anyone use these no-brand ball screws in a machine tool? I could not resisted the price. $27 with free shipping for a 16mm diameter by 550mm long ball screw and nut. There is no way to get detailed specs for theses so I bought one to evaluate. I was not expecting a lot for $27 but I was surprised. The nut is a pre-load design that is truly zero backlash and if there is any error it is less than what a low-end dial indicator can measure.
The eBay listing said "stainless steel" but it is hard to tell. I have a powerful magnet that sticks to the screw but it also sticks to about 1/3rd of my stainless steel kitchen cookware. I am making 3D CAD models of the parts because I could not find any on-line. I'll post them-line after I have verified them. What I am wondering now is if anyone has first hand experience with this product in a real machine. Mine is a 16mm diameter by 5mm lead screws 550mm total length with an SFU1605 ball nut. -- Chris Albertson Redondo Beach, California ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
