Rollix solutions for wind-assisted propulsion systems
Maritime wind?assisted propulsion is emerging as an essential solution for reducing fuel consumption and CO? emissions in the shipping industry. Behind these innovative technologies – rigid wingsails, rotors or automated sails – lie high?precision mechanical systems that are critical to their efficiency.
With recognised expertise in the field, Rollix offers a comprehensive portfolio dedicated to wind?assisted propulsion systems, built around two core pillars: custom slewing bearings and complete orientation modules.
Controlling the orientation of wind?assisted systems: a key performance driver
The efficiency of a wind?propulsion system depends on its ability to adapt in real time to changing wind conditions. This optimisation requires reliable solutions for controlling the orientation of the equipment.
Orientation systems must meet demanding requirements:
- high load capacity (axial, radial and moment)
- accurate rotation and positioning
- resistance to extreme marine environments
This is where Rollix solutions deliver significant added value.

Custom slewing bearings: critical components for wind?assisted propulsion
Les couronnes d’orientation sur mesure constituent le premier pilier de l’offre Rollix pour la propulsion Custom slewing bearings form the first pillar of the Rollix offering for wind?assisted propulsion on vessels.
Engineered specifically for each project, these maritime slewing rings provide the interface between the vessel structure and the wind?assisted system. They enable:
- smooth, precise rotation of wingsails or rotors
- optimised capture of wind energy
- excellent resistance to high dynamic loads
Thanks to bespoke design, they are perfectly adapted to:
- the dimensions of the wind?assisted system
- integration constraints
- performance and durability requirements
These components are essential to ensuring the reliability of wind?assisted propulsion technologies.
Complete orientation modules: turnkey solutions for maritime applications
The second pillar of the offering, complete orientation modules, provides an integrated approach tailored to maritime wind?assisted propulsion.
These plug?and?play solutions combine:
- a Rollix slewing bearing
- a drive system (motorisation, gearbox)
- mechanical and functional interfaces
Integrating these elements within a single module helps to:
- simplify the design of wind?assisted systems
- reduce technical interfaces
- improve the overall reliability of the system
Complete modules are particularly suited to manufacturers seeking optimised solutions for wind?assisted propulsion projects.ptés aux industriels recherchant une solution optimisée pour leurs projets de wind-assisted propulsion.
Solutions engineered for demanding marine environments
Wind?assisted propulsion equipment is exposed to harsh conditions: salt corrosion, humidity, temperature variations and significant mechanical stress.
Rollix solutions incorporate:
- corrosion?resistant materials
- dedicated surface treatments for marine environments
- high?performance sealing systems
This ensures long service life and optimised maintenance — two essential criteria for shipowners.garantit une durabilité élevée et une maintenance optimisée, deux critères essentiels pour les armateurs.
