ROD04000-040DA15-900-000 Large diameter bearing

Liebherr roller bearing slewing rings are suitable for medium to high loads. The linear load transfer allows them to transfer much higher forces in the same installation space compared to four-point bearings and makes them particularly suitable for larger diameters. Typical applications are mining excavators or large crawler cranes, offshore and mobile harbour cranes. Roller bearings by Liebherr have also been tried and tested in drilling rigs and deep foundation machines.
