Piston

Built for continuous heavy-duty service, the Piston (OEM 551 592 63) is a premium aftermarket component for rock drilling and drifter rigs operating in extreme conditions. As the core driver of percussive energy, it converts hydraulic pressure into the high-impact blows that fracture rock, making its dimensional accuracy and surface integrity critical to drilling efficiency.

Manufactured from premium hardened steel with precision-ground striking and guide surfaces, it withstands extreme cyclic impact loads while maintaining tight running clearances for maximum impact energy transfer. As an alternative replacement, it ensures reliable fit and function while offering significant cost savings over the original.

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.
