Learn How It Works

Why Chain Pins Seize

Production stalled, crew waiting, pressure mounting fast.

Torch risks sparks and damage in tight spaces.

Seized pins block restart—won't move under standard press.

Why This Happens

Corrosion builds over time, locking pins in bushings. Wear and contamination pack gaps, increasing friction under load cycling. Thermal effects and material expansion seize pins solid, stopping chain movement.

No torch required—eliminates heat and spark risks

Controlled hydraulic force extracts pins safely
