Description

Engineered around the operating needs of surface and underground drilling equipment, the Cylinder Tube (OEM 550 859 16) is an aftermarket component for the rock drilling machine assembly. It converts hydraulic pressure into controlled linear movement, helping position or actuate the connected mechanism with stable force and alignment.

It gives maintenance teams another sourcing path for the referenced application without compromising the need for dimensional and functional compatibility. Typical listed applications include DD311 and DD320-40, subject to machine specification and configuration verification. The working surfaces are designed around repeated pressure loading, with dimensional control supporting stable guidance and sealing performance.

Offered within Delkom’s aftermarket range for surface and underground drilling machinery, this part supports planned maintenance and international spare-parts supply. To confirm availability and fitment, reference Delkom 110 800 350 and OEM 550 859 16 when contacting the Delkom team.
