Review: Great pulleys for the price! - If you know what you're doing, these are great pulleys! Yes, the bearing cover does come off easily but it's a non issue if you design your axle to account for it. Used these to build a physics force table for my children. 3d printed support brackets and axle and voila! $30 dollar force table compared to $100 plus if you buy a premade table! Great pulleys! With so many, you can use it for all kinds of pulley applications.
Review: These were exactly what I expected. I ended up ... - These were exactly what I expected. I ended up not being able to use them for the application I had planned on due to their size being a little smaller than I needed, but I had no problem finding another use.
