Description

Suited to scheduled maintenance, repair and component renewal, the Piston (OEM 551 748 83) serves an important function in the feed and drill-carriage mechanism. Its role is tied to the high-cycle impact section of the drifter, where reliable fit and controlled movement influence energy transfer to the drill string.

This reference is catalogued for equipment such as DT821-C; confirm the exact application before placing the order. The geometry is intended to remain stable under repeated impact loading, supporting reliable interaction with the adjacent drifter components. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel.

Delkom supplies alternative spare parts for rock drilling equipment to maintenance teams across international mining and tunneling markets. When requesting stock status, technical support or a quotation, provide Delkom part number 110 800 501 together with OEM reference 551 748 83.
