Shaft seal for Demag AC700

The shaft seal, part number 75808279, serves as a dynamic sealing component within the mechanical assemblies of the Demag AC700 crane. Its primary function is to contain lubricants such as oil or grease within rotating shaft systems while simultaneously preventing the ingress of external contaminants like dust, dirt, and water. By maintaining the integrity of the lubrication barrier, the seal supports the operation of moving parts within the machine.

This component is specifically engineered for fitment on the Demag AC700 all-terrain crane. It is designed to maintain a seal against rotating shafts within gearboxes, transmissions, or other mechanical drive systems where precise tolerances are required to ensure the protection of internal bearings and gears. The design incorporates a sealing lip and structural reinforcement to maintain contact pressure against the shaft surface during operation.

Shaft seals are used in heavy machinery to manage the interface between stationary housings and rotating shafts. They are essential for preventing fluid loss and protecting internal mechanisms from environmental debris, which helps maintain the operational state of the drivetrain and hydraulic systems in large-scale lifting equipment.
