Spiroflow Chain Down: Seized Pin Won’t Press Out
Spiroflow chain-driven equipment stopped by a frozen chain pin.
Why pins seize solid
Line stalled, production blocked by a pin that won’t move.
Torch risks damage and safety issues under downtime pressure.
Corrosion, wear, and contamination lock pins tight in heavy service.
Why This Happens
Corrosion builds rust between pin and sidebar, seizing contact surfaces. Wear and contamination pack debris into tight tolerances under load cycling. Result: pin freezes solid, blocking disassembly and halting equipment restart.
