Stabilizer Piston

Built for continuous heavy-duty service, the Stabilizer Piston (OEM 551 528 82) 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. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.

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.
