How to install or replace Rollers on a web guides

Hi, this is Pedro Velasco with Roll-2-Roll technologies. Today I want to teach talk to you about how to install a roller on our web guides. Now in some situations you might have that you purchase a web guide from us but you require a special coating on your roller. Well we don't carry those in stock but we can tell you where you can find those rollers from one of our suppliers.

And so the best thing we can do is teach you how you change the roller or how you install the roller on your web guide. So when we give you a web guide when we send it to you you will have the shafts for the roller already installed so they're gonna be located here and they're attached with two m8 screws on each side. So just remove the m8 screws and remove this shaft. So this is one of our typical and groove rollers that we have in this case the roller will have when you receive it it will be covered in a black protective fabric and then it will have two rubber bands on the edge so you just take the rubber bands off and leave a protector protective fabric on it until you're finished assembling it.

But for so you will have on, either side, one side of the roller you will have a little bearing which is actually going to help it's a pressure bearing so it keeps a pressure on the shaft as you're assembling it. And then on the other side you will have two set screws that will actually lock the position of the shaft on the bearing. Now these collars kind of move around so they are pivoting collars. Okay so the first step to do is install the shaft into the the roller into the roller itself.

So you go through the collar that has the little bearing ball bearing on it and just carefully install it in there and just push it through right. Now it should go all the way through to the other side to the other collar and then you will have to look on it on this side just to align it. So once you have it aligned just push it through all the way up there okay so it goes out. Now one of the things you'll notice is we have to kind of center this shaft on the roller.

One of the best ways we found out is this measuring the distance between the end of the shaft to the on the on the roller. You could use the vernier for that. So we'll just take some measurements here. This one has a hundred point one six zero inches on one side and on the other side it should be very close to that.

It has point one eight one. I'm gonna measure that again point one eighty five. So what I do, this is pretty close to center, so what I do I just give it a little tap on one side and see how much it moved. Point one six six point one seven seven- that's close enough.

Okay so I have a ten thousandth of an inch difference between either side so that. So now we proceed to lock the shaft in place now the roller face will have a little cutout in it which is gives us access to these set screws. So you align the set screw to the to the cutout and just tighten it. Now for this you will need a 1/8 inch allen wrench.

so once you have it set and tightened then you can proceed to install the roller onto the roller plate. And this is a fairly simple operation just align the holes of the shaft to the holes on the rollerplate. Place your m8 screws on it just throw them on and just finish it off by tightening with a 5 millimeter allen wrench. And just give it a once you come to the lock just give it a quarter turn that'll be enough.

And you have assembled or placed a new roller on your web guide then you can remove this fabric and you're ready to go. So we hope that this helps you in doing a change of our roller assembly onto the roller plate and just watch on our YouTube channel for more instructional videos.
