Slewing bearings are widely used in construction machinery, such as tower cranes, excavators, mobile cranes, truck-mounted concrete pumps, etc. Rothe erde slewing bearing products accompany such
machines all over the world, the important things is that with the rapid development of India economy, which lead to a strong demand of various kinds of construction machinery. Rothe erde slewing
bearings can totally meet the need.
Metallurgical and mining equipments are characterized by their tough working conditions, like high temperature and heavy dust, they also need slewing bearings with hing load, then three-row slewing
bearing can be chosen and work well in these conditions. Slewing bearings for ship deck cranes are also required to meet the relevant marine product specifications strictly and be approved by the
corresponding Ship Classification Society. Medical CT scanner is an indispensable part in modern medical equipment, and now Rothe erde products play a crucial role in CT scanners. Rothe erde
slewing bearings also are used in wind turbines, offshore equipments, etc.
