Break Seized Chain Pins Fast — No Torches. No Hammering.
Stuck chain pins from scale-packed links are shutting down your foundry conveyor line now.
Why Pins Seize in Foundries
Scale, heat, and abrasion weld pins into the bores until nothing moves. Downtime climbs fast as seized links refuse to break loose under load. Hydraulic force is the only reliable fix when scale buildup locks pins solid.
Why This Failure Happens
Scale buildup packs tight around WH132, WDH159, and H-series pins, creating solidified debris that locks the pin inside the sidebar. Thermal cycling expands and contracts the joint, increasing friction and galling. High-impact loading then drives contamination deeper, freezing the pin until it will not press out by conventional methods.
