The large diameter bearings by Liebherr are available in a wide range of designs and sizes and prove their value every day in a large number of applications, for example in excavators, tower cranes, and wind turbines. Consequently, Liebherr followed up the Bauma by bringing a corresponding product catalogue onto the market. It does not only enable customers to select large diameter bearings for all types of applications both simply and quickly, but also provides information on the slewing and swiveling drives tailored specifically to the bearings.
The product portfolio for the standard series ranges from single-row four-point and double-row four-point bearings to double-row ball bearing and triple-row roller-bearing slewing rings, right through to a combination of both ball and roller elements. The bearings of the standard series are available in the diameter range of 800mm to 6,000mm, and can be delivered in all standard gear modules. For larger diameters, Liebherr offers segmented designs.
The product catalogue is also a design manual for the static and dynamic calculation of large diameter bearings and, with the help of a step-by-step guide, is simple and convenient to use. Detailed technical descriptions and specifications of the large diameter bearings are also provided. The contents also include Liebherr latest research and development methods, e.g. the assessment of the load distribution in the bearing on the basis of the adjacent construction, and the subsequent derivation of service life forecasts. In addition, the large diameter bearings catalogue contains the presentation of Liebherr's core competences in bearing design (bearing engineering), induction hardening, and surface protection, which are based on over 50 years of experience in bearing production.
