Question 45

What types of Rollix slewing rings do you offer (ball, crossed roller, Double Row, precision ranges, Compact CB)?

Dahou Kebich · Accepted Answer

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.
