Piston Rod

Description

Built around the service demands of rock drilling machinery, the Piston Rod (OEM 3222 2900 21) provides an aftermarket replacement path for the feed and drill-carriage mechanism. It converts hydraulic pressure into controlled linear movement, helping position or actuate the connected mechanism with stable force and alignment.

Accurate alignment of the sliding and sealing surfaces supports consistent extension and retraction while limiting premature seal and guide wear. Compatibility records include FLEXIROC D60LF and FLEXIROC D65 – 10 LF. For best results, check the part reference together with the machine model and serial data. The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost.

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 120 400 427 together with OEM reference 3222 2900 21.
