Ball Screw Nut TBI SFU1605 (Diameter 16mm Pitch 5mm) for CNC Machine Parts

It arrived safely with the inner tube intact. I didn't need the clear plastic tube to put it on the ball screw. I just lined up the black tube with the screw, pushed hard enough that it didn't move, and slid the nut over the top of the screw. It turned smoothly over the screw with no issues. I'm back printing again! I'll buy a couple more just to have them on hand.

I was able to load this screw nut on to a shaft without major difficulties. The arbor arrived slightly cracked, and had to be somewhat forced over the shaft, but by wrapping it with 1-2 layers of tape, the nut transferred on to the thread immediately. The fit is snug and the rotation is very smooth. Great quality for the price.

Bought this for the X Axis of my CNC router. Worked well for about 45 days. (About 20 actual jobs = 40 hours)Then mid-stream, started locking up. Acting like it had bad bearings. I checked and the seals looked okay. No apparent loss of ball bearings. The locking would happen at certain distances. (Not positions on the X) I am running this with two linier rails and a 1204 screw. I checked my rails and alignment which looked good. I replaced this unit with a spare I had from a previous purchase and it was back up and running.I will say that I did not add any additional lubricant to the ball screw. If that is recommended, I could not find the proper process or lube type for this screw.

So I originally bought a ball screw with the nut already mounted on it. As I was attaching the screw to the cnc the nut came apart...not sure how but the ball bearings went everywhere. So I decided to buy a new nut. It came with the tube inside that was zip tied in place. Problem fo me was that there are no installation instructions so I cut the tie to attach it to the screw. The tube came out and all the tiny little balls as well. I'm not sure what happened with the first one but some direction about not losing that tube when you screw it on the ball screw would have saved me having to get a 3rd one and alot of aggravation.

The arbor inserted in the middle did not fit my shaft. The clear plastic one included would have, but the dust cap ends were so distorted that that the clear one distorted when inserted and, balls everywhere. After three frustrating hours trying to repack the balls, I give this review. If your time is worth anything to you, use a different vendor.

i stupidly blew up the nut that came with my ball screw (over travel, balls fell out, could find them...) the reviews that said their nut arrived fallen apart have to be iffy because my came with the ball retainer zip tied tight in the nut and the little alignment tube fit snuggly on the 8mm shaft of the BS. the new nut screwed on cleanly without any issues.

The media could not be loaded.  Por el momento está funcionando bien, el husillo que compré para el eje z incorpora una de estas tuercas pero decidí poner una más para aumentar la superficie de contacto y evitar posible pérdida de precisión. Su desempeño es bueno y hasta ahora todo marcha sin problemas.
