20mm Linear Rail SBR20-600mm with SBR20UU Bearing Block, Linear Rail Guide Length 23.6 inch(600mm) for Fully suppoeted Shaft Rod

These worked great for my router sled

When I received these rails, I was very impressed with the quality material used for these pieces! These are perfectly machined and not made with flimsy, substandard materials. You just don't see this type of quality much anymore. They easily handled the load that I used them for (but rated much higher) - with very smooth gliding action. I can't say enough about the quality of these pieces - and at an affordable price! Would highly recommend these rails for most any application where quality is critical.

Used to make a router sled. Works great

Very little backlash or movement. Not sure it is use it for machinist precision, but excellent for wood working level precision.

as advertised and shown on Amazon. Packaging could use some redesign to "survive" shipping.
