3115535804 Damper Liner Piston Guide Shock Absorber for Epiroc Cop1838hd+ Hydraulic Rock Drill Drifter
3115535804 Damper Liner for Epiroc COP1838HD+ Hydraulic Rock Drill Drifter
Precision machined damper liner for Epiroc COP1838HD+ series hydraulic rock drill drifters. Manufactured from premium heat-treated alloy steel, this shock absorbing liner provides stable piston guidance, effective percussion buffering and reliable hydraulic oil distribution in demanding mining and tunneling applications.
Product Overview
The 3115535804 Damper Liner is a core wear-resistant and shock-absorbing component installed inside the percussion cylinder of the Epiroc COP1838HD+ hydraulic rock drill drifter. It serves dual functions: guiding the reciprocating impact piston and buffering strong percussion shock generated during drilling, while forming the critical oil distribution cavity for the drifter’s hydraulic system. Precision machined from high-grade alloy steel with advanced heat treatment, the damper liner maintains a stable piston running track, reduces vibration loss and effectively extends the service life of both the piston and the drifter front end under continuous high-frequency impact.
