What Kumera does

Kumera Corporation is a privately held Finnish industrial engineering company headquartered in Riihimäki with 501-1000 employees and manufacturing operations in five countries (Finland, Norway, Germany, Austria, and China). Note that the firmographics record lists the founding year as 1945 while the company-history timeline records 1975; both are reported as supplied. The company designs, manufactures, and services heavy-duty mechanical power transmission products, marine propulsion systems, and metallurgical process equipment, serving enterprise customers in mining and minerals, pulp and paper, metal industries, marine and shipping, cement, sugar processing, rubber and plastic, water and environment, and non-ferrous smelting verticals.

The core technology centers on industrial gearboxes (multi-stage helical, bevel-helical, single-stage helical, bevel, agitator, worm, and custom-built units), with capabilities including planetary speed reducers offering ratios from 224:1 to 144000:1, lifting capacity from 30 to 200 tons, and up to 50% mass reduction versus conventional designs. The marine division provides propulsion, hybrid, front-end, and angle gearboxes for engine power from 200 to 4000 kW plus controllable pitch propellers up to 4500mm diameter. Proprietary metallurgical process equipment includes the Steam Dryer (industrial standard for 20+ years, 30+ global references) and the Heat Recovery Steam Dryer (introduced 2021, delivering up to 40% additional drying capacity without extra primary energy). The group is vertically integrated through Peiron Oy foundry (approximately 5500 tons annual casting capacity, multiple marine classification society approvals), Kumera Machinery Oy (17,000 sq.m heavy subcontracting facility with ASME U stamp and PED certifications), and the Kumera Technology Center for R&D and engineering.

Revenue is generated through hardware sales (industrial and marine gearboxes, foundry castings), engineering services and project implementation for process equipment, and aftermarket service and original spare parts. Go-to-market is enterprise field sales with technical specification and direct customer engagement, supported by trade show participation (EXPONOR 2026 in Chile, SMM 2022 in Hamburg, Northern Industry Event 2024), a corporate website with PDF library, and the Power-Plaza online gearbox selection portal. All pricing is quote-based and not publicly disclosed, reflecting the custom-engineered nature of the products.
