Slewing rings

Guaranteeing the performance of your machines

Providing leading edge technology for your slewing rings since 1969

Rollix is a division of the Defontaine Group and offers a wide range of reliable and durable slewing ring available from 100 mm to 6,200 mm with or without gear, made of materials ranging from C45 to 42CrMo4, as well as more specific materials such as titanium and many other alloys.

Our unique raceway finish grinding process and precise pairing of each ring allow for optimal adjustment of the preload required for the application.

Since 1969, we have been continuously developing new technologies to meet the high performance requirements of our customers and to adapt to their application requirements. From construction to high precision markets, today we work together with over 3,000 of the most demanding customers in the industry.

  • Over 1 million rings installed worldwide
  • 95% of our production is exported to more than 65 countries on 5 continents

Advantages of the slewing bearing

The slewing ring offers a number of advantages over a conventional bearing assembly and is increasingly being used as a standard mechanical component. It includes reduced number of parts, simplified machining, quick and easy to assemble, reduced space requirements and decrease in total weight.

Rollix standard slewing rings

The quality and high precision of our products will ensure that your machines run smoothly and safely. Our range includes ball, cross roller bearing, and extends from standard slewing ring to customised rings according to your application requirements. Our design, research and development department, equipped with state-of-the-art test benches and calculation software, is at your service to offer innovative and adapted solutions.

  • Single or double row ball or roller bearings 
  • Slewing rings with external, internal, spur, helical gear or without gear
  • Steel, titanium, aluminium, etc.
  • Surface treatment and/or corrosion protection
  • Standard or specific seals
  • Lubricated-for-life rings, food-grade grease.

Rollix custom-made slewing bearings

Rollix can offer specific designs with a wide range of solutions: 

With or without fixing holes: an alternative between a bearing and a slewing ring. It is a hybrid assembly that enables a small footprint at low cost.
ROLLIX COMPACT: for precision applications

Rollix specific solutions

Rollix can provide specific solutions for all its products. Complete modules can be supplied. In this way, a “turnkey”, tailor-made solution is provided to meet your specific needs. Rollix can supply pinions, geared motors (with our associated partners), motor mounts or mounting brackets, and cylinders. We can also integrate measurement sensors and provide lubrication solutions if required. Complete assembly and testing can also be carried out to customer specifications.

In addition, if your application qualifies, Rollix can supply ots lifetime lubricated (-EV) version. This solution is based on Rollix seal technology and has been validated on our test benches. The advantages of this solution are a 50% reduction in maintenance costs over the product’s lifetime, a reduction in maintenance time, a reduction in pollution since no used grease has to be disposed of, and no grease stock management is required.

Finally, grease distribution systems can be set up to adapt the best possible lubrication solution to your system. Rollix offers lubricators fitted on the slewing rings. This is a system that can be connected directly to the lubrication holes screwed into the slewing ring holes. We also offer remote lubrication in the center of the slewing ring: extensions can be added if the environment prevents direct access to the slewing ring lubrication holes. Finally, our centralized lubrication with distribution will ensure that the lubrication is evenly spread across all the lubrication ports. Other solutions are also available, such as lubricating pinions.For any specific request, please contact the Rollix sales team.

How to choose Rollix slewing rings?

Our 6 steps process to seclect a slewing ring

  1. Estimate loads (see « slewing ring characteristics »)
  2. Pre-select the slewing ring range according to the determining criteria
  3. Verify the raceway’s static capacity and fasteners according to slewing ring range
  4. Check rotation speed
  5. Check forces on the gear
  6. Validate the slewing ring’s dimensional characteristics
