ANWOK Ball Screw SFU1204 RM1204-600mm 12mm Antibacklash Linear Motion BallScrew L600mm/23.62inch with Ball Nut End Machining CNC Part

The media could not be loaded. EDIT: I contacted the company about the ballscrew and they offered to send a replacement. Very quick shipping and the new one is perfectly straight. 10/10 customer service.The original ballscrew arrived bent with a deviation of 1.2mm per rev. Both the BFBK12 blocks and nut are good quality.

This shipped in a reasonable time and was the correct length. I ordered this to change the travel of one of the axis of my cnc that I build adding 100mm and the ballscrew and nut fit perfectly with my existing hardware. Unless you have proper end support i suggest you purchase the kit.

this item arrived quickly and was packaged nicely, only issue is my kit was missing the grease fitting and the bearing block on one end needed sanding down to fit onto the screw was about .003 of an inch too big and i couldn’t press it on

Using this as my z-axis and it's smooth as butter

No complaints on use for hobby CNC, no deflection issues, tolerances seem good. Well packed.

Skip includes all the bearings call Keds to put together a complete ball raced lead screw set up. Everything operates. Super smooth and well finished.

Very smooth action. A very good product for the price.Downside: should include a warning - DON'T remove the Ball screw nut or the bearings all drop out and is no longer useable (found that out the hard way)
