The green material in those pinch rollers is (I think) polurethane and it
eventually goes the way that yours have. There's no alternative but to
replace or have someone like Terry's rebuild using your roller's metal hubs
One of the problems with replacement pinch rollers these days is
manufacturers getting the hardness of the roller's original rubber right.
Ideally the hardness should be as per the manufacturers' original
specification for that machine/model, but after all this time it may not be
so easy to determine that figure, as original samples will have long ago
perished in one way or another.
After fitting the new/remanufactured pinch roller to the machine, and
cleaning and lubing the bearing as needed, it's advised to readjust pinch
roller pressure according to the relevent service manual.

Subject: [ARSCLIST] pinch rollers for Studer B67?
The pinch rollers on our two Studer B67 machines are disintegrating and I
would appreciate suggestions on where to get replacements.
I'm putting up a couple of photos of the state of our current rollers in
case anyone wants to take a look and tell me what is going on. The machines
are not used frequently (once every six months) and playing a tape the other
day seems to have started the breakdown or at least made it very evident.
The tape plays without incident on a Sony-O-Matic machine (APH version).
Thanks in advance.
