Description

Made for professional drill-rig and drifter maintenance, the Piston Rod (OEM 551 609 96) is positioned as a reliable aftermarket alternative for the percussion and drifter assembly. The assembly provides linear hydraulic force for positioning, clamping or support functions where repeatable stroke and controlled movement matter.

Cross-reference data lists applications including DD311 and DD311-40; final fit should be confirmed against the machine configuration or serial information. The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost. Accurate alignment of the sliding and sealing surfaces supports consistent extension and retraction while limiting premature seal and guide wear.

Delkom supplies alternative spare parts for rock drilling equipment to maintenance teams across international mining and tunneling markets. When requesting stock status, technical support or a quotation, provide Delkom part number 110 400 218 together with OEM reference 551 609 96.
