Description

Designed for consistent performance in heavy-duty drilling applications, the Piston Guide Rear (OEM 3115 1833 00) is a compatible aftermarket component for Epiroc drill rigs and related rock-drilling equipment. The rear piston guide supports and centers the percussion piston at the back of the drifter, maintaining the alignment required for high-frequency reciprocating motion. Listed applications include BOOMER L2D, COP 1440 and COP 1838, 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. Correct guiding clearance limits piston side load, reduces uneven contact and helps preserve the condition of the piston and bore through repeated impact cycles. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
