The Rotator Cylinder (OEM 985503-23008) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. It provides the pressure-sealed chamber that guides the piston and routes hydraulic energy through the unit.
Made from high-grade steel with a precision-honed bore, it endures high internal pressure and repeated loading while holding tight running clearances. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
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.
