Support Disk

Built around the service demands of rock drilling machinery, the Support Disk (OEM 551 712 28) provides an aftermarket replacement path for the undercarriage and tramming system. Its role is to support, cover or locate adjacent components so the assembly keeps the intended geometry during demanding field operation.

Controlled mounting geometry and durable load-bearing surfaces help preserve alignment while resisting vibration, impact and repeated machine movement. Application data associates this reference with DX700 and DX800; configuration and serial-number checks are recommended before purchase. For fleet maintenance, it offers a practical replacement route where dependable fit, serviceability and cost control are important.

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 111 000 169 and OEM 551 712 28 when contacting the Delkom team.
