Study and design of your industrial projects
Within the Defontaine Group, we offer our expertise in the industrial world and production processes to provide you with solutions adapted to your requirements.
Our team will offer guidance for your projects from design to manufacture while providing innovative and functional ideas. We also have several test benches specially dedicated to testing our Rollix slewing rings in real conditions.
Our areas of expertise
The design process for your industrial projects consists in several steps:
- Technical and financial study of the project
- 3D CAD design and drafting
- Design calculations
- Development of component specifications
- Development of rapid and functional prototypes
For your old parts, we offer:
- Inspection of your old parts
- Optimisation based on our expertise
Methods preparation includes:
- Monitoring of market-specific standards
- Creation of manufacturing processes
- Definition and production of manufacturing tools
- Support for operations performed by our technicians in the field
Rollix test benches
Based on our long-term experience complying with the high standards of the wind energy sector, we have developed our own test benches to ensure the optimum strength of our slewing rings, from the largest (>6,000 mm diameter) to the smallest (100 mm).
The Defontaine Group’s test benches are recognised by our customers and used for the Rollix brand slewing rings in all activities:
Our test benches allow us to test and validate the conformity of our designs and manufacturing processes. Our software allows our teams to perform calculations and record measurement results with micron-level accuracy. Test benches are essential and are used on a daily basis in the development of a product or a project, whether made to order or tailor-made.
These test benches make it possible to guarantee compliance with the requirements and standards of our various markets.

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.
