Excellent
Excellently machined worm pair. Exact to the specified dimensions.

Good matched gear set
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.

Good quality!
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 several of these on my 3D Printer
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.

unusable
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.

Come da descrizione.
Buona manifattura. Come descritto dal venditore: corona da 40 denti e rapporto di riduzione 1:40 (40 giri di vite senza fine per 360° di rotazione del pignone). Sono compresi 2 grani brugola per il fissaggio sui rispettivi alberi.

Bien taillé
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 ...

Präzises Pärchen
Die beiden Räder passen super zusammen. Auf meinen 5er Edelstahlwellen passen sie super drauf. Da wackelt nichts. Echt sehr präzise gefertigt.
