Liner

Created for continuous-duty rock drilling applications, the Liner (OEM 3115 5000 52) offers a service-focused replacement choice 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.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. For application accuracy, verify the OEM reference against the machine parts list, serial information or removed component before purchase. Controlled bore, rod and sealing interfaces help maintain smooth stroke behavior, pressure retention and resistance to side-load wear through repeated cycles.

This component forms part of Delkom’s alternative spare-parts program for professional drilling machinery. For current stock, commercial terms and technical cross-checking, quote Delkom part number 120 103 198 with OEM reference 3115 5000 52.
