Cylinder Cover

The Cylinder Cover (OEM 550 540 70) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. 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 and exports premium alternative rock drilling, drifter equipment and spare parts to more than 100 countries. Contact us for current availability, bulk pricing and technical support.
