This is the Atlas Copco cylinder part number 3121500300, Crowder SKU AC-3121500300. This is the main pressure housing of the rock drill. Because it wears against the piston, the two are normally inspected and replaced as a pair.
It appears on the RH 658L/LS/LS-01 Rock Drill breakdown. The tool itself is the RH 658 L Surface Rock Drill. Compare it to the reference callout on the diagram to be sure it is the position you need.
