Cost-Effective Operation
We use the best technology to accurately control hole size and pitch. That means longer wear life for chains and sprockets, reducing your operating costs.

Long-Lasting Construction
One-piece construction means bushings are stronger and last longer. You get more mileage from Union® Chain.

Built to Last
Our Welded Steel Chains are built to exacting Union® specifications using heat-treated premium-grade steel. Barrels are welded to sidebars to create the highest fatigue resistance in the industry.

Easy to Assemble
Chain pins are manufactured from high quality steels and through-hardened for maximum strength. Special design considerations include enlarged shoulders for tight press fit in the sidebars and tapered construction for rapid assembly.
