I did however get the impression that it was a relatively new change.

I've dug out my research from the Centa site and looking at the spec sheet for some broadly similar looking couplings they have 2 specs for the elastomer (roller) elements.

Centalan with a temp spec of -45c – 100C and HD which is -45C – 130C

So my assumption is that the original rollers were Centalan and the "new spec" will be HD.

Note, this is very much a personal assumption based on a spec sheet for a similar looking coupling and not based on any knowledge or discussion with MMC or Centa
