Excavator Undercarriage

The internally greased pin and bushing with seals offers several benefits over Sealed Track.

• Eliminates internal pin and bushing wear until the lubricant is lost.
• Minimum 25% increase in internal wear life because of less pin and bushing wear.
• Improves sprocket wear life because sprocket and link assembly pitch remains matched for a longer period of operation.
• Track noise is reduced because there is no metal-to-metal contact between the pin and bushing.
• Allows for enhanced undercarriage management opportunities.

The outer diameter of the bushing has been increased for Grease Lubricated Track and offers many benefits.

• Increases external wear life by 20% or more.
• Link life, normally limited by bushing wear, is better utilized because internal and external bushing wear life is extended.
• Overall system wear life is enhanced by 25% or more due to the combined improvements of internal wear, external wear and sprocket wear.
