Bar & Pin

Bar and pin chains are used in a variety of applications, from conveyors to tension linkages. They are utilized for economical installations where the speed is relatively slow and/or the lifting of enormous load is required.

Bar and pin chains consist of plain link bars assembled on, and bearing directly against, the chain pin. This type of chain does not utilize bushings or rollers.

Union® manufactures a wide range of sizes, materials, and ultimate strength ratings
up to 1,000,000 pounds.

Double Flex Chain rotates on two planes, making it an ideal choice for a wide variety of applications. The pin bearing surfaces and selected sliding surfaces are induction hardened for extended wear life.

The Double Flex Chain offers a large sliding area to decrease shear on the chain and the sliding surface because design allows maximum flexibility for both horizontal and vertical movement.

This versatility allows compact layouts and economical cost. The mechanically designed cupped shape of the outer link plates of DF-3500 and DF-3910 eases side flex movement and protect rivet ends. This feature also prevents pin wear at the ends. DF-3498 offers flexibility with straight outer link plates.
