Piston

Developed as an aftermarket replacement for professional drill-rig service, the Piston (OEM 3115 2126 00) is a high-quality aftermarket component for Epiroc drilling and mining equipment. It forms a core moving element in the drifter, converting hydraulic energy into the impact cycle required for rock drilling. Typical compatible references in the supplied list include COP 1838, COP 1838-1850CR-CRL and COP 1838CR-CRL.

Manufactured with controlled geometry and application-appropriate surface properties, it is intended to move accurately within the drifter and transfer energy repeatedly without disturbing alignment. This is especially important under high-frequency impact, rapid acceleration, hydraulic loading and continuous lubrication. Stable piston motion supports efficient impact energy transfer and helps limit abnormal wear on nearby guides and liners.

Supplied as a Delkom aftermarket alternative, this part is intended for professional maintenance and overhaul work. For ordering and cross-reference purposes, use Delkom reference 120 100 084.
