U.S. Tsubaki is the leading manufacturer of mining chains that are used in underground, above ground, and preparation plant applications. We currently manufacture many different sizes of mine chains for several major OEMs. This relationship enables us to design upgrades for the chain in the mining equipment to meet the ever-changing needs of the industry. We use alloy-grade steels, heat-treated to precise specifications and assembled with the heavy press-fits required to withstand the punishment of today's more powerful, high production mining equipment. Our complete line of mining chains includes: Shuttle Car Chain, Feeder Breaker Chain, Tram Drive Chain, Wash Box Chain, Drop Forged Rivetless Chain, and Jig Washer Chain. To better service your industry, nearly all of the mining chains are in-stock and ready for immediate shipment. We also manufacture made-to-order chains and attachment configurations for your individual requirements.
