Linear bearing is a low-cost production of linear motion system for unlimited travel in conjunction with the cylinder axis. Because of point contact between ball and straight axis, so the load is small. The ball is spinning with the smallest friction, it can run a high precision and smooth motion. Flange linear bearings can be divided into: round flange type, oval flange, guide wheel flange, guide the oval flange type, plus long round flange type.
This is the sliding unit with the aluminium case, shafts and aluminium rail for preventing deflexion. This is the complete sliding unit systems and can be clamped simply tightening by bolt with high accuracy. The support rail unit provides maximum rigidity and stiffness to the shaft throughout the whole stroke, and ensure the performance of the unit.
The shaft is case hardened. If you use normal steel shafts, the bearings will cut them up in no time. So make sure what you buy is case hardened!

The rails and slides are great but was hoping to use this for a router sled. The holes on the sliders don’t line up with holes on the rails so now that I’ve cut up the boxes I have to find another use for these. Don’t buy is planning for a router sled or attaching two sets together, it doesn’t fit.

Product looks and feels amazing, It was exactly what I was looking for. Customer support from this sell was excellent! I highly recommend not only this seller but also this item. The rails were spot on 12mm thick I look forward to using this product more in the future.

I was looking for a cheap linear rail to add sliding shelves in a chest for additional storage. They fit tight and glide nicely. The rails are aluminum so they cut easliy and clean. The carriages feel very robust and so far I have had zero issues with them.If you are looking for a cheap yet high quality linear rail, these are a perfect fit.

These things are beefy! They are also very heavy, so if you are trying to limit weight these won't work for you.Sturdy is the only word that comes to mind.
