I tested all ten of these bearings on my 8mm shaft. One runs smoothly in all directions, four support smooth linear motion but cause friction when spinning the shaft, and the remaining five give off a crunching noise and the motion is not smooth. Someone please do let me know if this is fixable. I don't know, maybe with grease or something.Package came in an antistatic blue bag, with pairs of bearings individually wrapped in plastic, generously oiled inside and out.

These replace the x/y/z bearings on your CNC printer.Came individually wrapped with a thin film of machine oil on.Some of these bearing are hard to get hold of and very expensive.These do work well but for how long only time will tell.Just make sure you have the right ones for your machine.

I'm really not sure about the quality of these but you get what you pay for. They honestly do the job just fine. Might not be perfect for like applications that require high tolerance. I put these on a 6 mm rod that I also bought from here and it fit perfect.

Well packed and arrived quickly.Just like everyone else with a SV06 plus, i was suffering with dry rattily bearings, no matter how much i tried to lube them they just were not right.Replaced them with the 10mm version of these and what a difference, filled them with as much lube as i could get in them before installation but well worth the price.Printer is now running as it should, quiet and smooth.

Half of the bearings I used had some ball bearings pop out when I tried to put them on the shaft

Maybe I received a bad batch, but these ran very rough on the rods even after thorough cleaning and lubrication. I was curious why, so I took one apart and the channels are only half full of bearing balls. I ordered the 4mm size.

They don't glide smooth. The best way I can describe the motion is crunchy and stuttery. Even after heavy lubrication. Definatly not for my needs...

I picked these up to replace some bearings in a 3D printer and they seem to move smoothly and silently. I tightened down the u-bolts that hold them in place and didn't notice any flex in the casing. So far, so good!

I ordered these HiPicco Linear Bearings for spare parts. I have two CNC machines which use the 10mm size linear bearings in the Z-carriage, so if the existing ones should decide to fail I'll be able to sway in these items. I can't comment on how well they perform, but they look pretty well-made. Although I ordered the 10mm size, this product is available in a wide range of sizes from 4 to 20mm in diameter.They don't take up much space to store until they're needed, so I see them as inexpensive insurance policies that'll let me get my machines up and running quickly should the need arise.

Used in CNC 3018 machine to reduce play. Worked well...could have been a bit more snug but still okay. A notable improvement over the original bearings.
