Learn How It Works

Why Chain Pins Seize

Production stays down until the stuck pin comes out.

Torch attempts risk damage and create fire hazards.

Corrosion, wear, and contamination lock pins tight under load.

Why This Happens

Corrosion builds between pin and sidebar, creating metal-to-metal bonding. Wear and contamination pack the joint, increasing friction. Repeated load cycling and thermal effects tighten the fit until the pin freezes solid and blocks disassembly.
