Review on CNCCANEN BallScrew 1605-350mm End Machine: High Precision with Ballnut Housing & Couplers BK/BF12 by Brad Ward

As another reviewer said, Excellent! It was packaged well, everything fitted together perfectly and the finish was to specification. There's even a grease plug in the ball nut (my other nuts from another seller don't have that). I haven't tried it on the car yet - it's included, but at first glance everything is fine. My only complaint is that the bearing in the BF12 is a bit stiffer than it should be. But nothing criminal - let's see how it works.
