3Dman GT2 20 Toothless Bore 5mm Aluminum Idler Pulley for 6mm Width Timing Belt 3D Printers (10pcs)

A couple of the bearing are a bit notchy, but that's not going to cause a problem for this application

I use these on 3d printersz and they're great for Gates GT2 6mm belts. A few of these came with dry, or rough bearings which was a pity. Otherwise they were decent quality, and the belt surface and aluminium outers were good.

3 of them had crunchy bearings in them. The rest were OK. We shall see how long they last.

they worked

Using these for T-screw Z-axis syncro. Just the job and good price for pack of 10.

Snabb leverans.

Upgraded my Ender 3 with these pulleys. The belt tensioners came with toothed pulleys which were a constant problem (layer shifts). The prints with these are absolutely smooth and works great. A highly recommended upgrade that's even cheap.

Tutto ok

envio rapido. parecen de calidad veremos lo que resisten

Come da descrizione, non brnridinite ke pulegge ma ottimo rapporto qualità prezzo
