Hello all, I'm new here and thought to see if I can ask for some help here on a project. Basically we're working on suspension trucks on a skateboard. I know nothing about skateboards when I first joined the group, but I'll be reading more on it soon. I'm trying to design a parallel scissor mechanism so the truck will only have one degree of freedom, which would be vertically. The mechanism would be mounted between the trucks and the bottom of the board. Shocks will be added to this mechanism later. I've looked on some bearings on mcmaster carr and we've decided to use the 5/16" outer and 5/32" inner size double-shielded steel ball bearings due to the limited space we have, but these could change depending on the load applications and testings we'll do later. This is one of the main problems I'm having. Must be silly questions, but what would be the best way to implement the bearings into the mechanism? If they were to go into the slots in the pics below, what parts/ways would be best? Are there any good websites that show how the joints and bearings work? Can't seem to find any sites that show detailed drawings of the bearings in slots. Thanks, I'm totally new to this. Will be modeling this in Solidworks and later machining at the shop.
