Key

Description

Developed for reliable operation during intensive drill-rig duty, the Key (OEM 344 738 11) is a compatible aftermarket component for Sandvik drill rigs and related rock-drilling equipment. The key locks a shaft and hub together so rotational force can be transmitted without relying only on friction between the mating cylindrical surfaces. Listed applications include AXERA 6-240, DD310-40 and DD311-40, with additional compatible models shown in the product data.

Materials and contact surfaces are selected to handle the wear, load, vibration and repeated cycling associated with mobile drilling equipment. Accurate width, height and seating are important for even torque transfer, minimizing local movement that can damage keyways or disturb the alignment of the driven assembly. Controlled dimensions support correct fit and dependable function during scheduled overhaul, wear replacement or corrective maintenance.
