Since many many many years sticky gummy wheels are being replaced with common off-the-shelf O-rings usually made of poybutadiene. They will probably outlast every other component of the calculator (and it's owner) while costing only a few cents (either Euro or Dollar) a piece.
Replacing the gummy wheels with metal is probably not a good idea because this will put a lot of wear on the cards, which, as you write in another thread, are on very short supply.


At least there’s another option.
