    I have a SORKZ with two distributor rollers which are damaged. The rilsan is coming off of them. These rollers are built into the press and have to be cut out. Does anyone know where I can get the replacement rollers that bolt back in place?

    Is the rislan peeling on the roller ends, or off the ends more into the middle of the roller? I've done successful small repairs of rilsan covered rollers, with a bit of epoxy, and a good deal of wet sanding with a fine grit sandpaper. The roller ends, I've not had much luck on and usually when they begin peeling its on the ends.
    Its been ages since working on Heidelbergs S line of presses but I seem the remember the older ones having a crank handle that goes into the roller journal and allows roller to disengage from journal for removal. Once removed you can have rilsan re applied!!!
    The other option would be to "side frame" the press to remove rollers and have them recovered with rilsan. I wouldn't recommend this unless you were having other work done while the press is apart. I think you'd only be "side framing" the inker.

    The rilsan is actually bubbling up and creating rolls. There is too much to repair. These rollers are before the crank handle.

    Yes, as stated above you would need to side frame only the inker if you want to recover the roller in the machine. Lots of work and I wouldnt suggest it unless you know what your doing. Easiest option is to cut the roller out and replace it with a 3 piece roller. My suggestion is to get the roller from Heidelberg. Might cost a little more but you get what you pay for.

    As stated by exheidmech.....you can cut the roller out....one method we use here is that we cut the journal of the rilsan roller and take it out, then you can do some alteration to the roller and make new journals which can be removed like the matte chrome cylinder in the conventional dampening system which is removed by opening hexagonal head screws.
    you can also recover the roller with a PVC pipe of the same diameter or a one which is close to it and it can easily be done on a machining shop.
    This will save you a lot of time and money.

    Seriously??? You have got to be kidding me! I would never do that to my own machine, let alone suggest it to someone as a repair for their machine. Unbelievable!

    OMG are you having a laugh......if you are going to make suggestions to people make sure they are viable, the Rilsan rollers are there for a purpose and are covered with that material for a reason

    There are thousands of printing units in Pakistan and no one imports rilsan rollers. PVC is a reliable 30$ fix and it works.... you believe or not....

    Whether the roller is covered with PVC, Rilsan, or whatever, it still needs to be cut out of the press and modified in order to bolt it back in. I'm looking for a roller supplier who has already made a replacement so that I can change the roller in an hour instead of having the machine down for a week or two.

    Just because it is common practice in Pakistan to use PVC as a roller repair doenst make it right and it definitely is not a repair to suggest to a credible company. Hey, if you wanna be a hack and make half *** repairs to your machine, knock yourself out. Dont expect your suggestions to be taken seriously in a forum like this with that kind of work. If you cant affort Heidelberg parts, maybe you arent charging enough for your printed product. If people dont wanna pay for your printed product maybe its because your print quality is not up to market standards. If your print quality isnt to market standards maybe its because you are making half *** repairs to your machine. And maybe at that point it is time to just close the doors and let someone that knows what they are doing take over.

    What would you say about the epoxy repair as mentioned by Turbotom.... is this a recommended repair?
    And with these half *** repairs we produce the quality work.
    Print buyers from US and EU come here just for quality work at cheap prices. They dont care if we are printing with pvc or rilsan rollers.

    Like I said, its your machine so knock yourself out. Not something I would admit to doing to my own machine let alone suggest it to someone else. Good day

    It was not an experimental thing that I suggested, it has been done over the years here. Good day;-)

    Does anyone know the exact diameter of the rilsan rollers for the SORKZ?
