WH78 Chain - Welded Steel Mill Chain
Buy it With:
WH78 welded steel chain is built for demanding conveying, drive, and elevating applications where strength and durability matter.
Each component is heat-treated and made from high-quality steel alloy to extend working life while keeping maintenance needs low.
For reliable operation, pair the chain with a WH78 sprocket that matches the chain pitch and application requirements.
WH78 chain is commonly used in heavy-duty conveyors, forest products, grain handling, pulp and paper, and sugar processing.
WH78 Welded Steel Chain Construction
Welded steel chains got their name from their construction. A welded steel chain is manufactured with a precision weld around the outside diameter of the barrel, connecting the two sidebars.
Within the barrel is a pin that is heat-treated a full 360° for optimal wear life. The assembly is completed by distinctive, heat-treated offset-style sidebars.

WH78 Chain: FAQs
What is the WH78 chain commonly used for?
This type of chain is made for jobs where strength and durability really matter.
You’ll commonly find it in heavy-duty conveyors, forest products, grain handling, pulp and paper, and sugar processing.
What is the pitch of a WH78 chain?
It has a 2.609-inch pitch, measured from the center of one pin to the next.
Getting the chain pitch right matters because the chain and WH78 sprocket need to mesh properly for smooth, reliable operation.
How do I choose the right WH78 sprocket?
Start by confirming that the sprocket is designed for the WH78 chain. From there, check the tooth count, bore size, hub configuration, and dimensions against your equipment.
Load, speed, shaft size, and available space can also help narrow down the right fit.
What sprocket options are available for the WH78 chain?
WH78 sprockets come in different tooth counts, bore sizes, and hub configurations, giving you flexibility when matching a sprocket to your equipment.
Made-to-order and custom sprockets are also available when a standard option doesn’t quite fit the job.
What attachments are available for the WH78 chain?
The chain can be paired with different attachments to suit specific conveying and material-handling needs.
Options include configurations designed for applications that need products or materials to be carried, pushed, or supported as the chain moves through the system.
When should I replace a WH78 sprocket?
Take a good look at the sprocket teeth. Hooked, sharp, uneven, or heavily worn teeth are all signs that replacement might be due.
While you’re there, inspect the chain too. A worn chain can shorten the life of a new sprocket, and the same goes the other way around.
