Over 15,000 Large Diameter Slewing Bearings Leave Liebherr Plants Every Year

The Group relies on 60 years of experience in the construction of slewing rings. As a competent partner in engineering and production, we are on hand to assist our customers worldwide. Our standard ranges from our own calculation models to state-of-the-art quality management.

Competent design and calculation

An eye on all influencing factors: The optimal design and calculation of the components is decisive for the reliability and durability of Liebherr large diameter bearings. Every single bearing is therefore comprehensively checked and evaluated for specific requirements in the development and prototype stage.

During the calculations using Finite Element Methods (FEM), our developers also take into account the adjacent constructions at the request of the customer. They perform a variety of individual calculations here

Modern processes and methods

The latest construction processes, simulation methods, as well as quality management tools, are used in the design and calculation of Liebherr large diameter bearings. Our own calculation models round off the spectrum of methods. Application-specific criteria are always the focus of making the design a reality. Our customers benefit from our complex application expertise.

High level of vertical integration and professional know-how

Liebherr impresses with a high level of vertical integration when it comes to quality-related process steps. This ranges from the machining and inductive hardening of the bearing raceways to the gearing of large diameter bearings through to the surface coating in-house. Professional know-how and our modern machine fleet characterise the entire manufacturing process.
