RENK Benelux – authority in marine gear systems
Our long-standing marine gearbox specialist Schelde Gears now operates under the name RENK Benelux. This step strengthens our presence in the Benelux market and brings RENK marine expertise even closer to our customers. RENK Benelux serves as the official sales and service representative for the RENK Group’s marine applications in the region.
For our customers, this means greater proximity, faster response times, and a dedicated service center in Vlissingen with highly experienced field service and design engineers. At the same time, continuity is fully ensured: Schelde Gears remains the official OEM for the design of Schelde Gears marine gears in the license market and for worldwide after-sales support. Existing contacts and structures remain unchanged.
As the legal successor of Schelde Gears and official RENK service station, RENK Benelux provides factory-certified engineering, design authority, and full OEM lifecycle support for marine propulsion gearboxes used in naval and commercial vessels worldwide.
