Creating a Functional Linear Slide Bearing in Autodesk Fusion 360

in this video i'd like to show you how to create a fully functional drawer slide such as the one illustrating the picture shown you can download these from many vendors this one has been taken from mcmaster car and has a 20 inch stroke so let's get started so what you're seeing is a download from a master car of my linear slide bearing now it's a bunch of bodies so you want to leave them in this position until we get them joined together so let's take a look at the bodies first i'm going to go ahead and look at the end view and rotate it around and zoom up a little bit now you'll notice there are some ball bearings and carriers they're only partial anyway we really don't need those so identify those as bodies and get rid of them to do that just click on them hold down the control key and click on them and find all of them there they are all of them highlighted now you want to right click and hit remove on top of one of them do not hit delete otherwise you will have some issues the next thing you want to notice is that there is a bumper at the rear that we want to be combined with the last section of track so go to your combine command which is under modify and pick on that bumper and the last piece of track you're going to join them together and end up making a new component because we're going to turn the other things into components also so say okay we have a new component now that body still remains and so does this one right there we want to get rid of that again remove that because it became a part of this component we don't need it anymore so we have two bodies and one component which consists of bumper the next step will be to make these two last bodies into components so again you can select both of them right click and say create components from bodies we now have all three components now we can join them together the next step we want to do is take some measurements so we can in get our joints in the right position so go to the end view again and then slightly move it off so you can see the back side and zoom up now if you have the windows multi-clip board you can be sure it's empty and we can place our measurements directly on the clipboard for future use if you do not have this installed just get out a piece of paper and write them down so we go to inspect and want to measure from this surface be sure you pick on the surface to this edge right there that is that number 2.2718 click on it to put it on the clipboard reset and do it again from this to that line right there and that number is there click again to go to the clipboard closure measure tool and then if you pull up your clipboard you'll see i have both those dimensions if not you got them on a piece of paper the next step will be add our slider joints so go to joints pick on slider if it's not already selected you're looking for the first one and that will be from this face that point now if you have trouble finding it just hover over the face and hold down the control key and will not go to any point except on this face pick this one that's the far back side then you want to go over to here again if you have trouble hover hold down the control key and pick the furthest one to the side it's going to flip on you so reverse it and then you'll notice it's moved it way back here so we need to move it back into position so that movement will be positive in this case so we'll click on that our windows clipboard and pick on this number whoops it's negative i apologize it is negative so i just go up here and add a negative real quick so it puts it in position and say okay that's your first slider next thing you want to do same thing a slider joint between again this point right there and this again hover hold down control key and pick that midpoint right there it flips on you flip it and then you want to hit again on negative so i'll just hit minus and my windows clipboard and pick up the last dimension it puts it into position say okay now you have both your slider joints in place at this point you can drag it around if you want but you notice it's not everything's moving so what do we need to do reposition it and then you want to ground this component in the back so right click on that component and ground it now you can slide your slider joint but it's not behaving correctly but we need to fix it so let's do that first thing you want to do is get this in the right position this stop hits against this so what i would suggest you do is use an align command from your drop down and modify pick on the back side of this face and then touch this face and they'll line up that is a flat to flat alignment so now we can add our linear limits to this so our next step is to add a limit to this joint movement right this slider the last one we did of 20 inches because again this is a 20 inch bearing so i right click on slider 2 if you did in reverse order to be different but edit joint limits minimum maximum now previously fill these in this happens to be the minimum is minus 20 because it's a negative movement and zero is the maximum yours could be reversed depending on your joint but anyway fusion requires you have the smallest number on top say okay and that will make this so it can go no further than 20 inches revert it back to position okay now the next thing you want to do is go in here and make a motion link between these two rails or these two joints there one slides half the speed of the other so we'll go to motion length pick on the two joints and we will make them two to one now you may have it backwards which i do so i'll make this one and there's two now you use any number that's two to one it doesn't matter it could be five and ten one to two whatever say okay now as you can see when you slide that joint it moves like a linear bearing would and it stops at 20 inches so you're all done you have a fully functional linear slide for your projects hope this helps you do better modeling in fusion 360.
