Snap ring for Demag AC 265

The snap ring, part number 50021398, functions as an axial retention device within the axle systems of Demag heavy machinery. It fits into a precision-machined groove on a shaft or inside a bore to prevent the lateral movement of gears, bearings, bushings, or pins. By maintaining these components in their correct orientation, the ring ensures the structural integrity and alignment of the transmission and axle assemblies during crane operation.

This component is compatible with the first axle of Demag AC 265, AC 395, and AC 615 all-terrain cranes, including the AC 395 Serie-76011 U150 model. It is a standard mechanical fastener used to lock rotating or stationary parts in place, preventing them from sliding out of position due to operational vibrations or axial loading forces. Proper installation within the designated groove is necessary to ensure the ring remains seated and effective under the mechanical stresses typical of heavy-duty crane axles.
