Poor quality is best for linear ball bearings

linear bearing relatively loose and very coarse. They seem to roll well when turning the shaft but bad for linear movement. But still you get what you pay for :) I think I was hoping for more but for my application it will work fine. I'm seeing if a little lube would help. What did I expect? --- A similar McMasterCarr product would cost ten times more. So I think I have nothing to complain about. In short, they will work for my application, but I don't need super precision.

Pros
  • linear bearing
Cons
  • Slightly wrinkled

Very poor quality power transmission products

Shafts, supports and bearing housings could be used but the bearings themselves were no longer needed. I wasn't expecting much given the very low price, but I was expecting at least something useful.

Someone suggested rinsing them with solvent before use, but that didn't help, at least not on the samples I got as the sand wasn't the problem. I took mine apart and the inner plastic rings were so torn that they were…

Pros
  • Industry and Science
Cons
  • unreliable

Staples are best sharpened in linear bearings

They are great for a variety of applications. My personal goal in purchasing this particular size is to increase the thickness of material that I can use on a 3018 cnc router as they are absolutely perfect for personal cnc modification, however I have a few complaints, my main complaint is the clips used to seal the packaging, they are sharp and poorly secured, i cut myself climbing into the box with other items. My other complaint is that there are no screws for the cushions, forcing the buyer
