Rollix has been manufacturing slewing rings for the marine and offshore sectors for over 30 years.
Rollix’s engineering and research and development departments are able to provide slewing rings specific to the needs of its customers: ball bearing and roller bearing technologies, or very high radial loads and high speeds (RLX-HDR). The rings are custom designed based on calculations including our finite element modelling.
Rollix slewing rings are used in a large variety of equipment: offshore cranes, pods or azimuth thrusters, gangway rings, seismic winches, subsea winches, FPSO buoys and floating wind turbine anchoring systems.
Rollix also actively participates in the design and delivery of prototypes and pre-production series for the wind-powered ship market, as well as in the electric propulsion segment. These designs are perfectly in line with the Defontaine Group’s sustainable development strategy.
Our manufacturing facility enables us to take part in projects supplying slewing rings up to 6,000 mm and compliant with DNV, ABS, BV, LLOYDS, GL, API and RS standards.
At Rollix, we have adapted and created a range of slewing rings designed to meet the constraints of the marine and offshore sector. Rollix’s engineering and R&D department offers products capable of withstanding marine constraints.
All Rollix parts are designed to withstand the marine environment with specific surface treatments and patented seals.
We design slewing rings for the marine and offshore sector. They can be fitted on the following machines:
The slewing rings are custom made up to 6,000 mm in diameter and can be adapted to meet specific requirements:
Rollix produces highly reliable quality products for maximum lifespan of the slewing rings.
Rollix has been manufacturing slewing rings up to 6,000 mm in diameter for over 30 years. We offer tailored solutions for marine professionals.
Rollix is a most valued partner of offshore and marine sector manufacturers, providing expert advice and guidance in the design and manufacture of your slewing rings. Our rings are used for offshore cranes, pods, gangways, winches, buoys, wind-powered ships or floating wind turbine anchoring systems. We are at your side to optimise your performance.

Slewing rings are classified into several main categories based on the rolling element, geometry and level of precision.
1. Ball slewing rings
Rollix offers several variants of ball slewing rings, designed for standard applications involving moderate to high loads.
• Single row of balls
Compact slewing rings, suitable for moderate loads and where space is limited.
• Double row of balls
Higher load capacity than the single row; used for more demanding machinery.
• Light series (L-shaped profiles or solid rings)
Designed for applications requiring weight reduction.
2. Crossed-roller rings
Crossed rollers provide high rigidity and a high load capacity, particularly for combined loads.
• Single row of crossed rollers
Capable of withstanding axial and radial loads in compact applications.
• Double row of crossed rollers
Even greater rigidity and capacity, used in cranes, wind turbines, forestry equipment, etc.
3. High-precision rings
Rollix offers ranges specially optimised for high-precision applications, such as robotics or indexing tables.
• Compact range
Very high positioning accuracy, available in a wide range of diameters (148 mm to over 2,400 mm).
• Compact Light
A lighter version of the Compact range, still designed for high precision.
4. ‘Compact CB’ slewing rings
Although the term ‘CB’ is not explicitly mentioned in the PDF, it generally refers to the Compact / Compact Light range, designed for applications requiring minimal space and superior precision.
5. Other complementary ranges:
• Three-row roller slewing rings
Slewing rings for extreme loads (offshore cranes, mining machinery).
• Hybrid slewing rings / thin sections
Alternatives combining bearings and slewing rings, for severe space constraints.
