Down Cylinder

The Down Cylinder (OEM 863 342 99) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. It provides the pressure-sealed chamber that guides the piston and routes hydraulic energy through the unit.

Made from high-grade steel with a precision-honed bore, it endures high internal pressure and repeated loading while holding tight running clearances. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.
