The ones purchased this time were usable, but the lifetime would be short The core of the bearing shaft and nut is 100μ Backlash is 10μ Previously purchased screw had a core circularity of over 1000μ Because it was eccentric processing, it was discarded because it could not be used 今回購入した物は　使えたよ　しかし寿命は短いだろう ベアリングシャフトとナットの芯円度は１００μだ バックラッシュは1０μ　 以前購入したネジの芯円度は1000μ以上だった　 偏心加工　されていたから使えずに棄てたよ

Bought this as a test sample for an upcoming CNC build. Very nice ball screw! Smooth movement all the way through. Also, the tilerences are extremely tight, and I even had to remove 1 micrometer from the fixed side for it to be able to fit in its end mount. Rather too tight than too loose. Very satisfied!

The 12x1 thread is not perfect surfaced. But usable. My spindle was covert in dirt when arrived. Check your spindels for dirt Else you will damage it.
