Description

Built for continuous heavy-duty service, the Stabilizer Piston (OEM 551 528 87) 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 produces premium alternative rock drilling and drifter equipment and spare parts, shipped to over 100 countries worldwide. Get in touch for stock availability, bulk pricing and technical assistance.
