Oil seal for Link-Belt LS-98

The AC81 oil seal serves as a barrier in heavy machinery to retain lubricants within a system while preventing the ingress of contaminants such as dust, water, or dirt. It is installed at points where a rotating shaft passes through a housing, ensuring that internal components like gears and bearings remain properly lubricated and protected from abrasive elements. The component consists of a sealing lip that presses against the rotating shaft to create a secure seal.

This part is compatible with the Link-Belt LS-98 crane, specifically for units with serial numbers 1LP-1382H and 1LP1461H. It is utilized in various applications across the machine, including transmission shafts, swing reducers, and cable drums, where maintaining fluid levels is necessary for system operation. Proper installation ensures the seal functions correctly within these assemblies.

Oil seals are generally used to prevent fluid leakage in mechanical systems. By maintaining a tight interface between moving parts and stationary housings, they help preserve the integrity of the lubrication system. This prevents friction, overheating, and premature wear of internal mechanical components, which supports the overall functionality of the equipment.
