Piston Rod

Description

Developed as a practical replacement option for hard-working drill rigs and drifters, the Piston Rod (OEM 551 555 57) is used within the percussion and drifter assembly. It converts hydraulic pressure into controlled linear movement, helping position or actuate the connected mechanism with stable force and alignment.

The alternative sourcing option is suited to maintenance programs focused on equipment availability, predictable servicing and competitive lifecycle cost. Compatibility records include DD311 and DD311-40. For best results, check the part reference together with the machine model and serial data. The working surfaces are designed around repeated pressure loading, with dimensional control supporting stable guidance and sealing performance.
