Radial shaft seal for American Crane 9260

The radial shaft seal, part number 180X140X17.5/21, functions as a barrier in the American Crane 9260 crane. It is installed at points where a rotating shaft passes through a housing to retain lubricants such as oil or grease while preventing the ingress of dust, water, and other contaminants. By maintaining a tight seal, this component protects sensitive internal parts like bearings and gears from environmental exposure and premature wear.

This seal features dimensions of 180 mm outer diameter, 140 mm inner diameter, and a thickness of 17.5/21 mm. It is specifically compatible with the American Crane 9260 crawler crane, ensuring the correct fit for the machinery's sealing requirements in the transmission or undercarriage assemblies.

Radial shaft seals typically consist of a metal outer ring for a secure press fit into the housing and an elastomer sealing lip that maintains contact with the rotating shaft. A garter spring is often integrated to provide consistent radial force, ensuring the lip remains effective under varying operating conditions. These components are necessary for maintaining the integrity of closed lubrication systems in heavy machinery.
