Pilot Cylinder Assy.

The Pilot Cylinder Assy. (OEM BG00228990) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. 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 a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
