Description

Made for professional drill-rig and drifter maintenance, the Shaft Assy (OEM 551 562 84) is positioned as a reliable aftermarket alternative for the rotation and drive train. It transfers or supports rotational and mechanical load within the drive train, helping maintain synchronized movement between connected components.

Concentricity, engagement geometry and load-bearing surfaces are important for smooth torque transmission and resistance to wear under repeated rotation. As an aftermarket alternative, it supports practical spare-parts planning and helps reduce dependence on a single supply channel. Compatibility records include DD321-40 and DD420-40. For best results, check the part reference together with the machine model and serial data.

Delkom combines rock-drilling spare-parts expertise with broad export capability for mining and tunneling customers. For purchasing support, bulk requirements or fitment confirmation, use Delkom reference 111 000 211 and OEM reference 551 562 84.
