Welded Steel Conveyor Chains – Overview & Applications
Welded steel conveyor chains are high-strength, rollerless chains engineered for abrasive, heavy-duty service. This guide compares welded vs cast (H-class) chains, outlines common applications, and shares best practices to maximize service life.
Construction & Design Features
Offset sidebars, welded barrel links, and fully heat-treated components deliver higher strength and wear resistance versus cast counterparts. WH-series chains cover a wide pitch range and run smoothly at speed.
Welded vs Cast Chains
Welded chains typically offer higher load capacity and durability than cast H-class chains. In most cases, welded chains run on the same sprockets as cast chains, simplifying upgrades.
Common Applications
- Forestry, lumber, and wood processing
- Pulp and paper mills
- Grain handling and agriculture
- Sugar processing and food bulk handling
- Mining and heavy material conveyors
Maintenance & Longevity
Routine inspection, appropriate lubrication, and correct tension/alignment extend chain life significantly. Consider replacing worn sprockets along with chains to prevent premature wear.
