Ich musste das Rad auf 6mm nachbohren, weil sonst es zu der Welle nicht passen hätte, aber es ist in Ordnung. Genau so, wie die Verarbeitung.Die einzige Sache die ich nicht gefunden habe ist die Abstand zwischen die Wellen.

The gear set curves helped to self-center. A little grease and friction isn't an issue because they set match very well. Precision, quality, hole center all good enough for my maker space.

Destiné à un entraînement horaire, l’engrenage a un bon aspect, à part un petit défaut sur la vis sans fin. A voir à l’usage ...

Surprisingly high quality - holes were a perfect fit on the appropriate shafts and the material is well-suited for low-torque applications. Shipped extremely fast.

Using these on belted Z axis (500mm) for my 3D Printer. Working well after applying some grease and pretty quiet even compared to lead screws.

What ever you do, do not purchase this item, it is not a worm and wheel. the worm has several straight groves in it, not a thread or spiral. It will not do anything as advertised. The worm will not turn the wheel as there is a fault in the manufacture. of the worm, ie it has groves not a spiral.
