• Specification

• Function 

1.The cylindrical structure supporting and guiding the track pin precisely mates with the chain link pin hole, maintaining pin coaxiality and positional accuracy, ensuring smooth transmission during tensioning and flexing of the track link.

2.Reducing friction and wear: The smooth inner wall, often equipped with lubrication channels or lifetime lubrication, reduces friction between the pin and the chain link, lowering power loss and extending component life.

3.Evenly distributing the load, the track bears and evenly distributes stress under heavy loads and impacts, avoiding localized wear and premature failure of the chain link and pin.

4.Preventing metal-to-metal contact, the wear-resistant lining isolates the metal surfaces of the pin and chain link, preventing seizure and strain, and improving system reliability.
