Learn How It Works

Why Chain Pins Seize

Corrosion and contamination pack the pin joint until it won’t move.

Wear and load cycling tighten clearance; the pin locks solid.

Production stays down until that seized pin is forced out safely.

Why This Happens

Corrosion builds rust that binds the pin to the sidebar. Contamination and material pack-out fill tolerances, locking the joint. Repeated load cycling plus wear reduces clearance until the pin seizes completely and blocks chain disassembly.
