Open the catalog to page 31. Introduction 1.1. Our company Defontaine Group was founded in 1946 around the unique technology of flash-butt welding. The group designs and manufactures complex mechanical parts and sub-assemblies. With three production sites (France, China and Tunisia), Defontaine Group is renowned for the quality of its products and its services, as well as for its loyalty and proximity to its customers and partners. The Rollix brand was created in 1969 to design and manufacture slewing rings and special bearings with outside diameters ranging from 100 mm to 6 m, with or without gear. Since its...
Open the catalog to page 41.2. Advantages of the slewing ring The slewing ring offers a number of advantages over a conventional bearing assembly and is increasingly being used as a standard mechanical component. These include: • Reduced number of parts • Simplified machining • Quick and easy to assemble • Reduced space requirement • Decrease in total weight...
