Seal ring for Komatsu D155

The seal ring 281-13-17150 functions as a critical barrier within Komatsu heavy machinery, designed to establish a hermetic seal between mating surfaces. Its primary purpose is to contain operational fluids or gases while preventing the ingress of external contaminants into sensitive assemblies. By maintaining the integrity of these interfaces, the component helps ensure that internal systems remain isolated from environmental debris and that pressure levels are preserved during operation.

This part is compatible with several Komatsu models, including the D155 bulldozer, the HD785 mining truck, and the WA420-3 wheel loader. It is engineered to meet the specific dimensional and functional requirements of the Komatsu equipment line. The seal is utilized across various systems, such as transmissions, hydraulic circuits, and axle assemblies, where it must accommodate the specific pressures and fluid types present in those environments.

In heavy machinery, seal rings are used to bridge the gap between stationary and moving parts or between two static components. They are essential for preventing the loss of lubricating oils or hydraulic fluid, which is necessary to maintain the operational efficiency of the machine's mechanical systems.
