Break Seized Chain Pins Fast — No Torches. No Hammering.
Engineered-class and roller chains fail when seized pins lock the drive mid-run
Why engineered-class pins seize
Dust, fines, and moisture drive rapid pack-out that locks engineered-class pins solid under load.
Thermal cycling, corrosion, and galling freeze pin movement until the chain stalls hard.
Downtime accelerates immediately once a seized pin stops the entire engineered-class run.
Why This Failure Happens
Engineered-class and roller chains such as WH124, WH132, and WR78 trap fines, moisture, and contamination between bushings and pins, accelerating galling and corrosion. Thermal cycling and load shocks deform pin interfaces and misalign joints until rotation stops completely. Once seized, the locked pin arrests movement and stalls the conveyor drive instantly.
Why Operators Choose Kingpin Breaker
Zero-torch removal prevents heat damage and safety delays
Hydraulic force breaks loose fully frozen engineered-class pins
Precision alignment protects chain bores during press-out
Field-portable design minimizes downtime during breakdowns
Works on WH-, WR-, WD-, and heavy roller-chain series for reliable recovery
