350-6311 3506311 Pin for 345GC 349 Excavator

Advanced Sealing and Lubrication Systems:

Sealed Joints: Most modern 349 pins feature advanced seal systems (such as Caterpillar's XT-3 or XT-5 bushing seals). These are multi-layer seals designed to keep abrasive contaminants (like dirt, dust, and mud) out and retain vital grease inside the pin/bushing interface.
Result: Effective sealing dramatically extends the service life of both the pins and the bushings by preventing contamination-based wear, which is the primary cause of premature failure in excavator linkages.

This 350-6311 pin is used for 345GC 349 excavator.
