AT 24/60 o-rings

[The EGE]

I just bought a Aerotech 24/60 system and a pack of F35-8W loads.

They included the following o-rings:

4x 13/16" OD x 1/16" thick
2x 5/8" OD x 3/32" thick

which are all in the instructions and parts list.


However, they also came with two 9/16" OD x 1/16" thick o-rings. I can account for no use for them. Am I supposed to use them, or were they an accident?

They are the delay spacer in lieu of a cardboard one.

PS - I asked the very same question and donaldsrockets provided this link. See part #11.

Thanks. I couldn't find it in a search.
