Damper Liner 3115535804 for Epiroc COP1838HD+ Rock Drill Mining Parts

The 3115535804 Damper Liner is a core wear-resistant and shock-absorbing component installed inside the percussion cylinder of Epiroc COP1838HD+ hydraulic rock drifter. It serves dual functions: guiding the reciprocating impact piston and buffering strong percussion shock generated during drilling, meanwhile forming the critical oil distribution cavity for the drifter’s hydraulic system.

Manufactured strictly in accordance with Epiroc OEM dimensional standards, this damper liner realizes direct plug-and-play replacement for original parts. Under rigorous underground mining, tunneling and quarry working conditions featuring heavy impact, high hydraulic pressure and abrasive rock dust, it stabilizes piston running track, reduces vibration loss and effectively prolongs service life of your whole Epiroc COP1838HD+ rock drill.
