Description

The Piston (OEM 701 301 20) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It is the central component that turns hydraulic pressure into the powerful percussive blows used to break rock, so its precision and finish directly affect drilling output.

Made from premium hardened steel with precision-ground impact and guide surfaces, it endures severe cyclic loading while holding tight clearances for efficient energy transfer. 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.
