Precision Bearing block slides.
Well made and easily installed. The four mounting points on the top are great to use to mount. They are light weight and should last quite a while. I also purchased the rail to make a complete system.

Very smooth motion
Great bearings to use with 20mm rods for linear motion. You will want to look for hard-chrome plating in any rod you use - otherwise the bearings will wear a track into the surface. Also look for supported rails with a T-type mounting facility that these bearings are designed around. 20mm round rod will not be straight over more than about 1 meter without support.
