About Jungbluth
Jungbluth is a medium-sized manufacturer of conveyor chains and sprockets based in Bad Hersfeld. The company primarily manufactures special chains in custom designs to customer specifications or develops application-specific new and optimized solutions; in addition, conveyor chains to DIN and ISO standards as well as sprockets and custom accessories for chain drives and conveyor systems are offered. Production is carried out in mild steel as well as in heat-resistant, low-temperature-resistant and corrosion-resistant versions, including stainless steel versions with plastic rollers. The entire value chain – design, production, assembly and after-sales service – comes from a single source. Sectors served include the steel industry, hydraulic steel structures, industrial furnace construction, the automotive industry, recycling and general plant engineering. Since 2025, Jungbluth has been a member of the Tsubaki Group (certified in 2025 as Tsubaki Jungbluth GmbH).
