Cobalt Chains is YOUR source for quality chains and components for the Sugar Industry.

In 2004, Cobalt Chains, Inc. was opened in East Peoria, IL by President and CEO Christopher J. Robinson. The plant

keeps in stock many of the popular chains used today such as: engineered steel, forged link, welded steel, ANSI

roller and transport chains to name a few. Cobalt Chains also fabricates their own chain, chain attachments and

sprockets in house. In addition to this, the company inspects and quality control tests each chain, sprocket, and

attachment that we manufacture. In 2016, Cobalt Chains saw the addition of a robotic welder to the facility. This

allows the company to produce 100% accurate welds.

When it comes to the Sugar Industry, Cobalt Chains produces the highest quality products such as: Welded

Steel, Drop Forged Rivetless, Main Cane & Auxiliary Carrier Chains and many more. This industry requires

products that can withstand the rigors of constant use with no down time. Our products are designed and man-

ufactured to not only stand up to this challenge, but also increase the efficiency of sugar mills in the process.

Today, Cobalt Chains offers the widest variety of chains to fit almost any application. The company has

excelled through the constant development of new markets and new product lines, to its enviable position

today as a true worldwide supplier of premium quality conveyor and power transmission chains. Cobalt Chains

is dedicated to its position as a world-leader in implementing the newest technology available in the conveying

industry.

● Drop Forged Rivetless chains are typically used asoverhead conveyors on automotive assembly lines, paint lines, appliance assembly lines, sugar mills and in the meat packaging industry.

● These chains have no rotating parts, therefore suffer less from the abrasion caused by sand/dirt, that can come into the mill with the cane. All parts and heat-treated and “T” pins ensure positive locking action in the sidebars.
