This resulted in a fundamental overhaul in the technology used to build rim-drives.


Insumo revolutionizes bearing technology for rim drive thruster applications. With its innovative approach, Insumo transforms the way bearings are designed and manufactured for rim drive thrusters, making them more efficient and reliable than ever before. The company's groundbreaking technology will set a new standard in the industry, providing unparalleled performance and durability for demanding applications.

For over 8 years, Insumo has dedicated extensive research to overcome the inherent vulnerabilities of rim drive thrusters. This commitment to innovation has culminated in the launch of the next generation rim-driven electrically propelled thruster on June 20, 2023, at the Electric & Hybrid Marine Expo Europe 2023 in Amsterdam. This groundbreaking technology represents a fundamental shift in the way these thrusters are designed, setting a new standard for the industry.

Magnetic Levitation

Insumo transforms bearing technology with its innovative approach. By replacing vulnerable mechanical bearings with magnetic levitation, Insumo introduces a game-changing concept that enhances wear resistance, energy efficiency, and stability. For the radial bearings, the new solution employs magnetic forces to keep the rotor in position, offering a long-lasting and stable alternative to mechanical bearings. In addition, Insumo has implemented a unique solution for the axial bearings by combining hard and soft materials, resulting in a longer lifetime compared to using just hardened bearings.
