Each individual component of the large diameter bearing is subject to strict quality requirements. This is why Liebherr only works with selected suppliers who are audited on a regular basis. Internal company standards apply to certain raw materials, for e.g. rolled steel rings. These standards contain requirements, which go beyond the common industry standards.

Liebherr not only makes regular use of traditional computer-aided measurement methods. The Liebherr Group also pos-sesses numerous highly specialised measuring devices. In recent years, for example, the company has invested in a state of the art crack detection system using high frequency magnetisation and a fully climate controlled large diameter bearing measuring chamber. 3D measurements of large diameter bearings with a diameter up to 6,000 mm can be effected. This type of measurement is unique worldwide.

The service life of a large diameter bearing is largely determined by the execution of the tempering process. With
state of the art system technology and in house developed inductors, Liebherr consistently achieves a high level of quality even for bearings with very large diameters. The degrees of hardness and the depths of hardness are subject to con-tinuous quality testing.
Certification and classification by internationally recognised approval authorities serve as an external benchmark of quality for Liebherr. Classifications and certifications of components and complete systems are common in the area of maritime applications and in the wind industry. If certain products are prescribed for this purpose, we assure on request that the necessary documents are provided.
