Which is the Best Pulley on Amazon?

In this video I'll be going over the 2 biggest cable pulleys I could find on Amazon. Comparing price, noise, quality and feel of them. Enjoy!

Nice video! I am not a DIY guy and I live in an apartment. I got rid of the dining room table and put in a very small gym. Part of that gym is a smith machine with a lat station attached. I am thinking of upgrading the lat station pullies to aluminum. I wasn't sure if the Amazon pullies would be good enough quality, but I guess they are.

Thanks for the info!

The 115mm aluminium with massive self made brackets are the best i tried. Mostly the worst part are the low quality bolts and the thin brackets. I would not trust them long term.
I´ve gone save and build 10 mm thick inox brackets with high quality bolts (i also weld it myself).
This will last longer than me.
On top i use quality swivels with bearings.

my question is whether or not the aluminium pulley would cause premature wear to the coating of the cable.

I have about a 1/4 gap on each side with the pulley inserted.
What would you fill that gap with..washers??

Thanks for the analysis. Where did you get the bracket that you put the pulleys in?

Your pulleys use ball bearings, either plastic or aluminum.
The noise of a bearing in a pulley will be manifested by several things:
Lubrication: a lack of lubrication favors the bearing of the pulley, it begins to be damaged and it will be noticed by the noise.
Load: if you use a few pounds in your exercises, the bearing on the pulley can last longer. if you use a lot of load (pounds) on the bearing in the pulley, that bearing in the pulley will shorten its useful life.
Pulley diameter: the greater the outer diameter of the pulley, the larger the bearing, and this is reflected in the fact that this bearing on the pulley supports a greater load.
You compared more used plastic pulleys with new aluminum pulleys, this is not a true test.
I tell you this because I know about bearings
