🔩 Efficient CNCCANEN Ballscrew Anti Backlash Housing Support: Minimizing Backlash for Improved Performance Review

As another reviewer said - great! 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.

Very good quality for the price. The end of the BK-12 case had 0.005 radial clearance, but I was expecting that. I'm going to use this on a CNC router and switch the bearings to angular bearings. However, I put two 0.2mm shims between the original bearings and the end play is reduced to about 0.0005 which surprised me, but I'm still planning on replacing them with AC bearings. Excellent packaging. I will buy from this supplier again.

This ball screw has exceeded my expectations. The triple packaging is protected by several layers of bubble wrap. Then stuffed tightly into a thick, hard cardboard tube. Then in a square box, not to mention a thin layer of oil to prevent rusting. With impeccable steel quality and a precise fit, you might think it's Made in Germany. I plan on buying a few more different sizes to get started. my automation of my woodworking tools.
