Ordering by number: this is 3111005700, the Atlas Copco buffer. It takes the recoil load so the surrounding parts do not. Compression set is the usual reason to change one.
It is called out in the parts diagram for the BBD 15E ET Rock Drill and CP 0022KL Rock Drill, and on 2 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the parts breakdown index has the full breakdown library, and the Atlas Copco lineup covers the machines themselves. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
