The Union® Chain Division of U.S. Tsubaki Inc., supplies top quality conveying and power transmission chains to the forest products and paper processing industries throughout the world. In these industries, dependability is key. That’s why you can rely on the Union® Chain Division. We incorporate innovative engineering and proven manufacturing techniques to create every chain. Union® chains stand up to the harshest environments, giving you economical service and combining greater strength and longer wear life with consistent dimensional accuracy, pitch after pitch.
Welded Steel Mill Chains and Attachments
Welded Steel Mill Chains from the Union® Chain Division are designed to efficiently convey wood chips, sawdust, ashes, garbage, and other bulk materials. Our chains combine greater strength, higher impact resistance, and longer wear-life to withstand the punishing shock loads and abrasive conditions in the forest products industry. For added convenience, the chains are ideally suited for welding in the field.
Welded Steel Drag Chains and Attachments
Welded Steel Drag Chains move very heavy loads. Like Welded Steel Mill Chains, Drag Chains combine strength, precision, impact resistance, and wear resistance. This versatile and economical chain is built to withstand punishing shock loads and abrasive conditions to provide longer wear life in your operation.
Drop Forged Rivetless Chains
Union® Drop Forged Rivetless Chains serve many functions in the forest and paper processing industries. You’ll find our chain in overhead conveyors, ash handling applications, and various scraper conveyors—anywhere tough, dependable material handling is required.
Digester Chains
We offer chains with 12" to 20" pitch for digester applications. Because these chains have direct exposure to an alkaline slurry of paper fibers, we follow rigid specifications for special corrosion resistance. Digester Chains are carefully manufactured on a made-to-order basis to meet your specifications. Contact Union® Engineering for your specific requirements.
Gull Wing Conveyor Chains
We have two styles of Gull Wing Conveyor Chains. Gull Wing Chain with a single, centered strand of chain, is ideal for moving paper rolls. Any pitch size can be produced with a variety of working loads. Gull Wing Chain with Outboard Rollers is an excellent way to customize your application. We offer rollers and bearings with a variety of materials and heat-treating possibilities to stand up to extreme conditions and load requirements.

Put machinery access at your fingertips. ONE-TOUCH INSPECTION DOOR® is a dust- and rain-tight inspection and service door for conveyors, as well as processing and handling equipment. These pre-fabricated units are in-stock and ready-to-go for easy installation at the job site.
