WH78 Welded Steel Chain: Features, Uses & Buying Guide

WH78 is a popular small-pitch welded steel mill chain that often replaces H78 cast chains, delivering improved strength and wear life in abrasive service.

Key Specifications & Design

Approx. pitch 2.609″, offset sidebar construction, welded barrels, and heat-treated pins, bushings, and sidebars for consistent performance.

Applications

Common in forestry/logging conveyors, agricultural handling, grain systems, pulp and paper, and other moderate-duty industrial conveyors.

WH78 vs H78 Cast Chain

Welded WH78 offers higher tensile strength and better fatigue resistance than H78 cast chain and typically runs on the same sprockets for easy upgrades.
