Description

Intended for equipment that operates under repeated load, vibration and contamination exposure, the Chuck (OEM 550 602 90) supports the percussion and drifter assembly. 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.

Accurate fit and robust working surfaces help maintain energy transfer and alignment through the high-frequency load cycles produced during drilling. Typical listed applications include DS311 and DS411, subject to machine specification and configuration verification. 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 110 102 236 together with OEM reference 550 602 90.
