[13pcs of Pack] Openbuilds Stainless Steel V-Slot Wheel 625zz Bearing Pulley Metal Double V Gear Aluminum Extrusion 3D Printer Parts

i dont add photos sorry. but these went on extremely easily on my anycubic chiron. i planned to use them just for the bed but ended uo getting tweo bags and upgrading all axis. i have a few left over ill use for another project but these are really nice. i felt it may be better more accurate setup on my chiron and so far it is! its a nice upgrade but not as expensive as linear rails.

Very quiet and no more roller warping. I love them.

These wheels are a huge upgrade in precision over pom wheels. It doesn't require a lot of tension on the to get the carriages snug with no play. The wheels are cut very accurately and seat fully in the extrusion V slot. All axis are super ridgid in comparison to the stock wheels, especially the Y Axis. For those who are worried about wear on aluminum extrusions, I don't think there is a problem. The spec sheet on their website states a Rockwell of 30-43 for the steel wheels. 6063 Aluminum extrusion is Rockwell 53. Unless you really crank them down I don't think wear is an issue, and since the steel wheels are softer than the aluminum, it's likely that the wheels will wear first. The only drawback is the weight. However the increase in rigidity and ease of install is totally worth it. Great product.

I installed on one of my 3D printers as it's promoted as being higher quality than the rollers it's currently using. I've spent hours and weeks trying to get these to properly seat. Finally thought I got them seated properly and started a print. Walk back to check and the coating and frame are being rubbed away. Immediately removed from machine. Here's to hoping the extrusions are well enough they don't permanently damage the older wheels I put back on.

Inicialmente el resultado del desempeño sobre mi impresora 3D Artillery Genius pro fue muy bueno, sin embargo, el metal de las redas posee una dureza tan elevada, que al final empezó a degradar el perfil de aluminio por el contacto por rodadura, tuve que removerlos de inmediato, las ruedas son de buena calidad que incluir en su descripción que son para impresoras 3D con perfiles de aluminio me parece publicidad engañosa que al final solo causará daños. / Initially the result of the performance on my Artillery Genius pro 3D printer was very good, however, the metal of the nets has such a high hardness that in the end it began to degrade the aluminum profile due to rolling contact, I had to remove them from Immediately, the wheels are of good quality, including in your description that they are for 3D printers with aluminum profiles seems like misleading advertising that in the end will only cause damage.
