Description

The Piston (OEM 3217 9203 14) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. 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. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.
