Explore our primary line of high-load slewing rings and structural rotation bearings optimized for Rotterdam's heavy maritime infrastructure and offshore installation systems.
Designed to absorb extremely high axial loads, radial loads, and tilting moments. Widely utilized in offshore wind pitch systems and heavy-duty port lifters across Dutch harbors.
Features integrated external spur gear systems for robust torque transmission in high-capacity deck machinery, crane vessels, and mining applications in northern Europe.
A low-friction, high-speed solution developed for lightweight material handling, packaging machinery, and AGV platforms operating in Dutch automated distribution hubs.
Highly customizable single-row ball bearing utilizing induction-hardened gear teeth. Perfect for excavators, water purification tanks, and general mechanical assemblies.
Netherlands’ aggressive expansion into North Sea offshore wind power demands high-durability yaw and pitch bearings. These bearings must withstand continuous wind forces, corrosive salty moisture, and heavy dynamic loads over a 25-year operational lifecycle.
The Port of Rotterdam—Europe's largest sea hub—relies on high-capacity container cranes, dry-bulk unloaders, and heavy-duty stacker-reclaimers. Our three-row cylindrical roller slewing rings supply these setups with the structural safety margin required for non-stop cargo operations.
Dutch automated agriculture leads the world. Lightweight, gearless swivel bearings provide the precise rotation necessary for high-density planting machines, conveyor loops, and sorting robotics that run within these highly efficient glasshouses.
