What ZOLLERN does

ZOLLERN is a German family-owned industrial manufacturer founded in 1720 and currently controlled by the Hohenzollern family in its 11th generation, operating as ZOLLERN GmbH & Co. KG with its headquarters in Sigmaringendorf-Laucherthal, Germany. The company operates two main divisions: Metals and Shaping (castings, forged parts, special profiles and finished parts) and Drive Technology and Automation (gearboxes, winches, electric motors, hydrostatic bearing systems, rotary table systems, and automation/special systems). Core technologies span seven casting methods (vacuum investment, open air investment, sand, Croning/shell, ceramic, continuous, and centrifugal casting), copper and copper alloy forging, hydrostatic and aerostatic bearing systems, planetary gearboxes, and permanent magnet synchronous torque motors with up to 2,200mm diameter and 100,000Nm torque capacity.

The company serves demanding industrial applications across heavy industry and mining (tunnel boring, construction machinery, mining equipment), marine and offshore (vessel cranes, port machinery, SOLAS-certified equipment), precision manufacturing (CNC machining centers, grinding, milling, turning), recycling and material processing (shredders, extruders, presses), and industrial process equipment (sugar mills, conveyor systems). Sub-brands include Dorstener for sugar mill gearboxes and Rückle Eimeldingen for rotary tables and automation. Manufacturing is distributed across Germany (Sigmaringendorf, Herbertingen, Laucherthal), Slovenia (Ravne), Portugal, and India (Sangli Service Center), with sales and service coverage across Europe, North America, and Asia.

ZOLLERN generates revenue primarily through custom-engineered hardware sales and project-based one-time orders, with quote-based pricing that is not publicly disclosed. Distribution is conducted through direct field sales to enterprise industrial customers, supported by regional sales offices, service centers, and a website-based inquiry system. Operational certifications include ISO 9001, ISO 14001, ISO 50001, and NADCAP Welding (Laucherthal). Recent product additions include the ZOLLERN Drive Guard condition monitoring platform and the TorqSafe overload slipping clutch, and the company is investing in India-based service infrastructure and standardized modular product designs to expand addressable market reach.
