Liner

Engineered for dependable service in demanding drilling environments, the Liner (OEM 3115 5358 02) is a compatible aftermarket component for Epiroc drill rigs and related rock-drilling equipment. The liner provides the guided working surface for the damping-piston section, helping the damping system control movement and absorb reaction forces within the drifter. Listed applications include BOOMER S1D, COP 1840+ and COP 1840EX+, with additional compatible models shown in the product data.

Materials and contact surfaces are selected to handle the wear, load, vibration and repeated cycling associated with mobile drilling equipment. A consistent bore and wear-resistant contact surface support smooth piston travel, stable damping behavior and protection of the surrounding housing during repetitive percussion cycles. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
