Bushing

Supporting maintenance teams working in abrasive, vibration-intensive environments, the Bushing (OEM 551 946 41) is used in the rock drilling machine assembly. By maintaining the working clearance at a loaded interface, it helps reduce metal-to-metal wear and supports more consistent movement.

As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Accurate fit helps distribute load across the bearing area and maintain the intended clearance as the connected mechanism cycles under load. Cross-reference data lists applications including DD311 and DD321-40; final fit should be confirmed against the machine configuration or serial information.

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 110 200 216 and OEM 551 946 41 when contacting the Delkom team.
