Linear Bearing Slide Box

This part can be used to make a simple linear slide.
1. The channels on one side accommodate 6mm diameter steel bearing balls.
1. The static side accommodates 3mm diameter screws so it can be attached to another extrusion.

You may want to slide the sliding side partially over the extrusion and then slip the balls into the channels Once the bearings are in, slide the part fully, and place screws in the extrusion so that the part can't slide off completely.
