Stiebel

What Stiebel does

Stiebel is a privately held, family-owned German manufacturer of industrial gearboxes and drive systems, headquartered in Waldbröl, Germany, with origins dating to 1900. The company operates through two legal entities, Stiebel-Getriebebau GmbH & Co. KG (the manufacturing arm) and Stiebel Ing. Service GmbH & Co. KG (engineering services), and employs between 251 and 500 people. Its product portfolio is organized around two core segments: Mobile Hydraulics — featuring P2000 and P3000 series pump distribution gears with forced lubrication, high-alloy steel gearing, and thermally optimized housings for mobile working machines — and Conveyor Technology — including the QuarryMaster and QuarryMaster HighPower gear motors (18.5–750 kW), plus S2000 heavy-duty units and A2000 shaft-mounted gear units. Stiebel complements its standard catalog with custom-engineered special gearboxes and an online QuarryMaster Configurator that enables made-to-measure product specification and quote requests.

Technically, Stiebel's differentiation rests on proprietary engineering features: forced lubrication of splined hollow shafts to prevent fretting corrosion, thermally optimized housings that eliminate oil cooling in most applications, integrated torque support and oil-lubricated backstops, and the highest variant diversity in the pump distributor gear market. The company maintains TÜV-certified ISO 9001:2015 and ISO 14001:2015 management systems across both legal entities, holds the 'Sicher mit System' (Systematic Safety) seal, and supports customers through a 24-hour hotline, spare-parts service, and dedicated engineering team.

Stiebel generates revenue primarily through direct B2B sales of hardware (gearboxes, gear motors, drive groups, and special solutions) to industrial OEMs and end users in mobile hydraulics, quarrying, mining, port handling, and material handling. Pricing is project-based and quote-driven rather than publicly listed; the online configurator funnels customers into direct sales engagement. The company markets itself through trade fairs (notably bauma China 2026), multilingual downloadable catalogs, and direct technical consultation, with no disclosed distributor or reseller network. Customers are described as 'leading manufacturers worldwide,' though specific logos, revenue splits, and customer counts are not disclosed in available data.
