Oil seal for Link-Belt LS-98

The oil seal, identified by part number FM3, serves as a sealing component within the mechanical systems of the Link-Belt LS-98 crawler crane. Its primary function is to retain lubricant within assemblies such as transmissions, axles, or bearing housings while simultaneously blocking the entry of external contaminants like dust, dirt, and moisture. By maintaining a clean and lubricated environment, this seal helps protect internal components from premature wear.

This component is specifically engineered for the Link-Belt LS-98 crane, including units with serial number 1LP-1382H. It is designed to meet the dimensional requirements necessary for the lubrication points on this specific model of crawler crane.

Oil seals generally consist of an elastomeric element and a tensioning spring designed to maintain constant contact with a rotating shaft. This configuration creates a barrier that maintains fluid tightness even during operation. In heavy machinery, these seals are used to isolate lubricated systems from the surrounding environment, which is necessary for the proper function of rotating shafts and gear assemblies.
