WAMGROUP Chain-Driven Equipment Down: Seized Pin Won’t Move
Your line is stopped because the chain pin is seized and won’t press out.
Common Causes of Pin Seizure
Every minute of downtime costs thousands while the chain stays locked.
Torching risks burns, fire, and equipment damage under breakdown pressure.
Corrosion, contamination, and wear make pins freeze solid, blocking restart.
Why This Happens
Chain pins seize from corrosion buildup, abrasive contamination, and repeated load cycling that packs material between pin and bushing.
