Unloader Piston

Description

Built for continuous heavy-duty service, the Unloader Piston (OEM 2635 5881 93) is a premium aftermarket component for rock drilling and drifter rigs operating in extreme conditions. 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. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
