Our range of ball bearing slewing rings supports both axial and radial loads and overturning moments. We supply low, constant-torque products with a unique raceway finish grinding, preloaded to optimise the load capacity and the service life of the ring. Rollix ball bearing slewing rings are tested on our benches and have become a worldwide reference over the years, guaranteeing 100% reliability.

Our range of single-row ball slewing rings are used in hundreds of applications.

Ball bearing slewing ring

Our cross-roller rings are ideal for application conditions requiring both high rotation accuracy and stiffness. The crosswise arrangement of the cylindrical rollers in the raceways allows our rings to support loads in all directions.

Our range of cross-roller slewing rings is used for applications ranging from heavy duty robots to the world’s tallest aerial lifts reaching 100 metres, where stiffness ensures operator safety.

Ideal for applications handling high loads, the two rows of balls increase the load capacity of our rings and particularly meet requirements for high overturning moments. The simultaneous grinding finish of both raceways ensures optimum preload and torque. Our range of double-row ball bearing slewing rings is the market standard for wind turbine blades, shipboard and offshore cranes.

Double-row ball bearing slewing rings

Our Heavy Duty (HD) rings are specifically developed for applications requiring high axial or radial load capacity combined with overturning moments.

The positioning angle of the rollers is precisely calculated with respect to the forces, depending on whether they are mainly axial or radial, also allowing a high speed of rotation without overheating.

Special seals are available for dusty environments in mines or corrosive atmospheres on ships and offshore platforms. Our range of HD rings has proven to be reliable and guarantees full customer satisfaction even under the most extreme conditions.

ROLLIX HD: slewing rings for heavy loads

Our range of heavy-duty slewing rings is used for offshore cranes, offshore winch systems, azimuth thrusters, bucket-wheel excavators, large mining excavators, etc.

Discover our range of light series rings with L-shaped rings or solid sections. Their slimmer and lighter yet robust design is ideal for standard applications. Our rings are interchangeable with standard market products, and are also available with or without mounting holes depending on the required application. They are available in 3 preload ranges, and are suitable for a wide range of applications, providing an efficient and reliable solution at an optimised cost.

Our LIGHT SERIES slewing rings are used for turntables or light load handling systems.
