Im sure there are a few on here who've comprehensively destroyed barrels... enough for them not to be suitable for repair.

I haven't checked all my cylinders but one of my RC valve axles only had a lump of silicone on the end. At that time I couldn't figure out why, but now I know that the bushing is missing totally.

I guess, in other cases, it could also be worn down, so you have to change it.

Does anybody have the dimensions ? Material ?
