slewing bearings

Large-diameter bearings

A global leader in slewing bearings supply, thyssenkrupp's Bearings unit started its production activities in January 1978, when Robrasa (former name of the company) was inaugurated. Since then, it has focused its work in manufacturing, recovering and special machining of this type of bearing.

thyssenkrupp provides bearings with diameters from 300mm to 3750m for highly complex applications in transportation equipment, civil construction, cranes, measuring equipment, excavators, construction machines, wind turbines, among other segments.

The company is also a reference in services, with a portfolio ranging from technical assistance to installation supervision and life cycle monitoring to bearings recovering and machining .

Present in 10 countries, thyssenkrupp's Bearings unit has plants in Brazil (Diadema - SP), Dortmund and Lippstadt in Germany; Great Britain, France, Italy, Spain, USA, India, Japan and China.

Applications

The slewing bearings and rings produced by thyssenkrupp are used daily in important facilities as structural elements and also in the elements of mechanical engineering, i.e. cranes, excavators, aerial and telescopes, bearings for aerospace equipment, offshore technology, trains, subways, tunnel excavators, wind turbines, underwater turbines and solar power plants.

thyssenkrupp and wind power industry

wind power bearings

The winds that generate energy also move Brazil's economy, which already has about 300 wind farms, mostly in the Northeast. Half of the installed towers have components produced by thyssenkrupp. The company supplies five bearings for each installed turbine: three for the blades, one for the tower, and the other one is used in the turbine rotor. Due to its large dimensions, the turbine is considered a particularly complex construction, and requires high technology and added value.

In addition to being a strategic partner in developing the industry, thyssenkrupp also pioneered in the early technical contributions to the country’s wind energy, supplying components for the first tower installed in Brazil. The unit was installed on the Fernando de Noronha archipelago off the Pernambuco coast, and has a wind turbine equipped with the company's bearings.

Power generation from renewable sources such as wind is one of the main challenges for the development and diversification of the Brazilian energy matrix, as it ensures security of supply with more sustainable and competitive procedures. thyssenkrupp has been operating in the slewing bearings segment in Brazil for 40 years, and is proud to maintain a level of excellence and innovation in its products
