![]() The brass part adds a bit of cost to the part too. Your manufacturing goes from one hole straight through to a precise drill part way down (maybe it’s in the mold of the plastic truck). I can see a lot of potential problems though. Smooth rollers with setscrews/locking-clamps are generic and can also be used as rope pulleys or axle spacers or other motion hw.C-channel (without V notches) is generic and multi-purpose, but would be confusing to stock compared to the U shaped ‘c-channel’ available now.Without the C crimp, its hard to avoid these obstructions, and hard to keep the rollers contained. Need some care to allow rollers to pass by screwheads inside the track that attach to the next level of slider. The edges of the two rollers can touch and roll against each other, since the front/back rollers rotate in opposite directions. Upper stages of sliders are tilting forward, held from flopping forward only by the moment arm of the distance between these two pair of axles. Right drawing shows that each roller only rolls on one edge of C.Use 2 pair of rollers for each stage, one pair rolling on each edge of C, to provide the ‘length’ of the slider that keeps the moving part from rotating away from the track.Left drawing shows top view of nested vertical slides (ala jpearman cascade linear lift), only top front roller shown.Now the rollers can be connected with an axle to keep both sides rolling together at the same time, like a herman-miller-brand office shelf flipper lid. Since the v-notches every 5 spaces on the C channel are now dents in your rolling surface, cut uniform v-notches all along the edge (like rack teeth) and notch the rollers into gear teeth to match them, and make the axle hole square. Here is an idea for linear roller system:įor a track, imagine a 1x2 C channel, crimped from U shape to C shape: insert a 0.4x0.9" iron mandrel and crimp the edge uniformly over the whole length.įor a roller, imagine the tank-bogie wheelset or the winch pulley riding on the crimped edge. ![]()
