The Slide Cylinder (OEM 985503-21055) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It forms the pressure-containing chamber that guides piston movement and channels hydraulic energy through the assembly.
Manufactured from high-grade steel with a precision-honed bore, it withstands high internal pressure and cyclic loading while maintaining tight running clearances. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
