GT2 Idler Pulley Timing Belt Pulley 20 Teeth 4mm Bore for 3D Printer CNC 6mm Width Belt Pack of 10

I use to replace Y axis idler on CR10 and CR10s so far very happy

Very well made. No issues.

The product looks OK as expected but the lack of bubble wrap protective packaging resulted in some damage to some of the pulleys. A bag is not adequate.

Good parts at a great price.

Bearings are suitable, but the width of the pulley varies from 9.0mm to 10.1mm. These are unusable for 10mm belts. Ordered replacement for a different vendor.

Eight out of the ten pulleys that arrived were unusable because the width of the belt track was less than 10mm and the belt would bind in the channel. The belt channel ranged from 9.83mm to 10.93mm width n this set of ten. One out of ten would be bad, but 80% failure out of the box? There is clearly no quality control at all in this factory.

The bearings seem fine (no grinding or sticking in my test). However, like so many other manufacturers, they forgot the inner shim, so it will bind once the pulleys are tightened down. One possible solution would be to use lock nuts to secure them, as this will remove the need to squeeze down on the bearings when securing them.

Various internal widths from 9.79 - 11.01 about half of these are to large to fit in the part as designed. Need to order more from a different distributor now.

Bought 1 and received 1/10 pulleys with broken teeth, returned it and bought it again.What a mistake, now I have 2/10 with broken teeth.

Prese per cambiare quelle della anycubic Kobra, perfette, mille volte meglio di quella schifezza che monta di default la stampante.
