The link rod provides yield strength of 800MPa, impact flexibility of 800kJ/m2 and center hardness of 22HRC~25HRC. High strength CO2 gas shielded welding is used to ensure the strength of the link mechanism. The internal liner is made of spheroidal graphite cast iron, guaranteeing self-lubricating function when the bucket link is working.
Since tipping links are not bushed, the bores will eventually wear out and need replacing. Damage to both bucket links and tipping links can result from bucket pins coming adrift during digging, or from fouling on items such as lifting chains. Damaged links should be replaced immediately to avoid further damage to the bucket, dipper arm, and bucket ram.
For your convenience we stock the tipping links in pairs, and the bucket links without bushes, giving you the option of re-using bushes where they are still in good condition.
