Measurement and machine processing of the contact areas
It is generally the case that not only must the contact construction for rothe erde® slewing bearings be of a torsion and bend-resistant design, but the contact areas for the bearing mounting itself must also be mainly flat. thyssenkrupp rothe erde recommends using an optical device or laser measurement device to measure the contact areas before a slewing bearing is installed.
Mechanical reworking
Mechanical reworking
If the measurement values are outside of thyssenkrupp rothe erde tolerance range (see table 1 under installation, lubrication, maintenance), mechanical reworking is recommended. In some cases, difficulties are encountered when processing large-scale companion structures. However, the use of transportable processing machines can help here. This also applies to upper constructions and overhead machining.
On-site work
On-site work
thyssenkrupp rothe erde carries out this work on site and in adherence with thyssenkrupp rothe erde tolerance ranges for well-known companies. A reference list of these companies can be requested from thyssenkrupp rothe erde. The ideal installation conditions for slewing bearings are steel/steel contact.
