Was impressed by how decent these are. Fit my 16mm shaft super nice. My application (basically a die shoe) required high precision and my thinger-dinger is supported/guided by four vertical 16mm shafts, with one of these linear bearings mounted to each corner.Zero play whatsoever. Glides smoothly. At least as good as was expected.I've used Thompson brand in the past. They are great. A bit better than these - but way way way more expensive. But also made in USA and not by the communists.Saw a 1-star review below explaining they tried to use these as an "axle bearing for an electric kids car"......well... that's 100% the incorrect application and use for this bearing. This bearing is designed to accommodate LINEAR motion along a shaft - not bear the radial loads of an axle.Play stupid games - win stupid prizes.

Very poor. Shaft wipers not touching the shaft, I made my own with felt washers. Bearings run quite rough. Mounting holes not aligned on square grid. Had to mark holes one by one.

Bought as an axle bearing for an electric car for the kids. The entire barrel is low quality plastic. As soon as the is any sideways tension on the shaft the shaft will not rotate inside. Might be good for a decorative thing.

These came last night are absolutely perfect for the use I have in mind! Currently working on the design of a 'cyclecar' and these will make the pivot bushes for the foot controls....they take a 12mm shaft and have needle roller bearings (with a seal)..... a lot better than the plain bushes I was planning to use!!

Well made linear bearings, with a nicely machined metal housing. Suitable for 3d printers or other light CNC machines. . These are a square base with corner chamfers The mouting holes are approx 4.5mm

3 out of 4 of the bearings I received were crunchy on the same rod.

These roll well on 1cm aluminum shafts and don't leave a ton of wiggle-room for rotation. They come very well oiled so no issues with rust getting in any time soon. The flanges for attaching these to something are fairly small so you'll need to be a little careful with clearances between the screw holes and the hole for your shaft to travel through on your connected part. That's not an issue if you're attaching to something rigid like aluminum but if you're going to use these for something plastic (such as 3D printed parts) just know you'll need to be a little mindful there.

Using these over a 10mm carbon tube, they are surprisingly smooth and well lubricated out of the box. Fit was perfect with no binding. They are not silent, but not really noisy either. Works well for the price.
