Our FIRST high school robotics team used a pair of these as the basis for a lift system that stacks and carries 40 pounds of plastic totes. The parts are nicely finished and work smoothly. A very reasonable price for a complete rail system of this quality.

We use the linear bearings to make a kind of track on wich a safety gard slides on to protect the operators on lathes in a machine shop.
Good product
