Track adjuster piston seal for Link-Belt LS-2700

The KRA-0616 track adjuster piston seal acts as a sealing component within the hydraulic tensioning system of the excavator. Its primary function is to create a seal around the piston inside the tensioner cylinder, allowing hydraulic fluid to apply the pressure required to maintain the correct tension of the crawler tracks. Proper track tension is necessary to prevent track derailment and to manage the wear of undercarriage components such as rollers, sprockets, and links.

This component is specifically engineered for the Link-Belt LS-2700 excavator. It ensures that the tensioner cylinder maintains the hydraulic pressure needed to adjust and hold the track tension during operation. By preventing hydraulic fluid leakage from the tensioner cylinder, the seal helps maintain the stability and mobility of the machine on various terrains.

Piston seals of this type are used in hydraulic cylinders to separate fluid chambers and maintain pressure. They are designed to function under dynamic conditions, accommodating the movement of the piston while preventing bypass leakage. When a seal fails, the resulting loss of hydraulic pressure leads to slack in the track assembly, which can affect the overall performance and alignment of the undercarriage system.
