Fiellberg

What Fiellberg does

Fiellberg Oy is a privately held Finnish designer and manufacturer of highly engineered hydraulic cylinders and related hydraulic systems, founded in 2015 by Managing Director Juha Elonen after acquiring the rights, drawings, and complete historical design archive of bankrupt predecessor Nurmi Hydraulics Oy. The company specializes in custom-built cylinders for demanding applications, with a primary vertical in marine, offshore, and subsea markets, and additional offerings across industrial (NTS 6-series), mobile (FTS 5-series), and specialized segments including district heating slide tubes, torque motors, complete hydraulic power units, and — most recently — Fiellberg Stabilizers hydraulic legs for recreational vehicles (launched July 2025). Technology development centers on hybrid and electrified actuation, including the patent-pending Power Module digital-hydraulic device, the EU-funded Electric Cylinder (FEC) launched in 2023, and improved telescopic pumps for wave energy developed under the Eurostars LOCWEC project with Wavepiston.

Fiellberg manufactures in three countries — Finland (Riihimäki headquarters, Vantaa, and Ikkala), China (Fiellberg Fluid Technologies (Dalian) Co., Ltd., opened 2019), and Poland — and sells through a hybrid model combining direct enterprise field sales by the Managing Director for global accounts with regional channel partners: Dometrics, Inc. in the US/Canada and Rautic GmbH in Germany. Pricing is quotation-based on custom specifications, with the company committing to respond to inquiries within one working day. The firm holds ISO 9001:2015 certification from DNV GL across Finnish and Chinese operations (achieved 2018, renewed 2020) and an AAA Finnish credit rating achieved in 2019 (top 3% of Finnish companies). The company tripled sales in its second fiscal year (2017) while maintaining profitability, and continues to invest in R&D through collaborations with Aalto University and Tampere University of Technology.

Core offering

Fiellberg designs and manufactures highly engineered hydraulic cylinders, ranging from one-off custom units to short-lead-time small-batch and OEM-volume production, with its core strength in demanding marine, offshore, and subsea applications. The portfolio also includes hydraulic systems and pump units, torque motors, district heating slide tubes, the patent-pending digital-hydraulic Power Module, the Electric Cylinder (FEC), Pro Canvas protective equipment, aftermarket spares (including legacy Nurmi Hydraulics products), and the new Fiellberg Stabilizers product line for recreational vehicles.

Product overview

Fiellberg is a designer and manufacturer of highly engineered hydraulic solutions with both custom and standardized product offerings. The core portfolio centers on hydraulic cylinders available in three standardized series: NTS 6-series for industrial applications, FMS-series for marine and offshore, and FTS 5-series for mobile applications. Complementing the cylinder lineup are complete hydraulic systems and pump units (from fractional motors to 500 HP diesel drives), torque motors for demanding rotary applications, and district heating slide tubes for energy infrastructure. The company also offers specialized products including the Power Module (digital-hydraulic hybrid for energy savings), Pro Canvas (cylinder protection equipment), and Fiellberg Stabilizers (hydraulic stabilizers for recreational vehicles). Fiellberg further serves the aftermarket with spares and replacement parts, including legacy Nurmi Hydraulics products. Manufacturing spans Finland (Riihimäki headquarters), China (Dalian facility), and Poland, with recent expansion into electric cylinder technology (FEC).

Broad incumbents

• Liebherr (Components): Liebherr's components division manufactures hydraulic cylinders, slewing bearings, and gearboxes primarily for its own equipment (cranes, construction, mining) but also sells to OEMs. It is a broad incumbent that overlaps with Fiellberg on hydraulic cylinders but competes via integrated captive demand rather than custom-engineered OEM supply.
• Parker Hannifin: Parker Hannifin is a large diversified motion and control technologies company with a substantial hydraulic cylinder and hydraulic systems portfolio serving industrial, mobile, and aerospace markets. It is a broad incumbent competing against Fiellberg in cylinder manufacturing but across a much wider product range and customer base.
• Bosch Rexroth: Bosch Rexroth is the global market leader in hydraulics, offering hydraulic cylinders, pumps, valves, and complete hydraulic systems. It is a broad incumbent that overlaps with Fiellberg on hydraulic cylinder design and supply, but operates at vastly larger scale and across all industries rather than specializing in custom-engineered short runs.
• HYDAC International: HYDAC is a major supplier of hydraulic components, systems, and services — including cylinders, accumulators, valves, filters, and condition monitoring. It is a broad incumbent that overlaps with Fiellberg on hydraulic systems and components, though it focuses more on system integration than custom cylinder design.
• Eaton: Eaton's Hydraulics business manufactures hydraulic cylinders, pumps, valves, and complete systems for industrial, mobile, and aerospace applications. Like Bosch Rexroth and Parker, it is a broad incumbent that overlaps with Fiellberg in cylinders but competes via scale, brand, and integrated system sales.
• Dana Incorporated: Dana is a large mobility and drivetrain supplier producing hydraulic cylinders, gearboxes, and sealing products for on- and off-highway vehicles. It is a broad incumbent that competes with Fiellberg on hydraulic cylinders for mobile applications but at much larger scale and broader geographic reach.

It is a direct peer to Fiellberg because both manufacture custom and standard cylinders with comparable mid-sized industrial customer bases.
• Hänchen Hydraulik: Hänchen Hydraulik is a German specialist manufacturer of hydraulic cylinders and dampers, particularly known for high-performance and engineered cylinders in industrial and test applications. It is a direct peer to Fiellberg because both are mid-sized, custom-engineered cylinder specialists competing on speed and engineering flexibility rather than scale.
• Bucher Hydraulics: Bucher Hydraulics is a Swiss-headquartered specialist in hydraulic cylinders, pumps, valves, and power units serving mobile and industrial markets. It is a direct peer to Fiellberg because both design and manufacture hydraulic cylinders as a core business, with comparable customer profiles in mobile hydraulics and material handling.
