Special project

The World Clock in Berlin

Since 1969, the World Clock (German: Weltzeituhr) has been turning on Berlin's Alexanderplatz 24 hours a day, seven days a week, 365 days a year. The “Weltzeituhr” has been the central meeting point in the city for Berliners and tourists ever since. In its shadow, the course of history changed. In 2015, the World Clock was placed under a preservation order - not only the clock, but also its technology. For over 50 years, a rothe erde® slewing bearing has ensured the smooth operation of the iconic timepiece on the Alexanderplatz, and thanks to the highest quality standards, it has done so as reliably as the proverbial clockwork.

Oil and gas conveying technology

350,000 tons under control

As part of an ultra-deep offshore project off the coast of Angola, oil deposits distributed over an area of 800 square kilometres and situated up to 1,950 metres below sea level, are being tapped. Around 300 kilometres of underwater pipelines connect two Floating Production Storage and Offloading Units (FPSO), in which both of the world’s largest slewing bearings are used. These roller-bearing slewing rings with a diameter of 18 metres allow for ships to be safely connected to the seabed and thus, to turn around risers. To achieve this level of precision under the harshest conditions, the gigantic bearings were individually designed and manufactured, in close coordination with the customer.

Precision applications

Precision over light years

The radio telescope, ALMA, is located around 5,000 metres above sea level on the Chajnator Plateau in the Atacama Desert in Chile. The 66 antennae with a diameter of up to 12 metres can even precisely locate and track stars and planets light years away. Yaw and elevation bearings enable the precise aiming of the antennae under extreme operational conditions: 70 percent air humidity, high salt content and changes in temperature of up to 40° Celsius.

Transport and conveying engineering

A quantum sea

Several products made by thyssenkrupp rothe erde can be found on one of the largest cruise ships in the world: In addition to roller bearing slewing rings for the rudder propellers and coupling rings for the gearbox unit, we have supplied slewing bearings and rings for the lookout capsule, “North Star”. The capsule made of glass can be pivoted 250° thanks to our bearing, providing passengers with a breathtaking 90-metre-high view over the sea. The main challenge when building this was the need for heavy loads to be moved in the smallest of spaces. A special sealing system and a sea water-resistant layer were developed to prevent the salty sea water from causing corrosion.

Construction and infrastructure

The largest drilling machine in the world

In order to drill Hong Kong’s deepest, longest, and largest underwater tunnel the largest tunnel boring machine was used. The gigantic mixshield with a diameter of 17.63 meter, is driven by a rothe erde® slewing bearing.

The production of this type of bearing takes place based on a concrete load spectrum, consisting of axial and radial forces, resulting tilting moments and eccentric axial or radial forces. It is also important to take the speed and duty cycles, as well as the required service life of such a high-performance bearing into consideration.

Raw material extraction and processing

7,000 tons in movement

With a tare weight of 700 tons and a bucket volume of over 40 cubic metres, the excavator moves 7,000 tons per hour on average. thyssenkrupp rothe erde supports difficult opencast mining assignments with its special bearings, which withstand the harsh operational conditions, and whose reliability is not impacted by dust or dirt.

Smelting works engineering

Roller bearings in a new dimension

One third of Czech steel production is represented by Třinec Iron and Steel Works. This makes it all the more necessary to avoid unnecessary systems downtime. thyssenkrupp rothe erde supplies a customised solution for steelworks converters with a special two-part design which makes installation during operation possible. Since the machine is operated under extreme temperature conditions, the double-row tapered roller bearing is also particularly resistant to heat.

Renewable energy

The largest main shaft bearing in the world

We are driving the energy revolution: We manufacture slewing bearings especially for the main shafts of wind turbines - on- and offshore. The mass-produced main shaft bearing which is currently the world’s largest has a diameter of 4 metres and has been ordered from thyssenkrupp rothe erde by well-known customers from all over the world. Maximum quality and reliability are the most important features of our rothe erde® main shaft bearings.
