Large diameter bearings

At Bauma China 2016, the Liebherr Components division presents its expanded large diameter bearings portfolio. Liebherr’s large diameter bearings are available in a variety of shapes and sizes for different applications. In addition to the standard series with a range of diameters from 800 mm to 6,000 mm Liebherr now offers larger diameters in single-piece as well as segmented versions.

The robust and economical design of single-row four-point bearings offers a high degree of operating safety and is insensitive to changes in the shape of the adjacent structure. These bearings are used in a wide range of applications, where, for example, they enable the swivelling motion of excavators or the rotation of tower cranes. They are also used as drive components of large rope winches.

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.
