LDB Slewing bearing

/in /by

LDB Slewing bearing is a kind of rotating rolling element bearing or sliding bearing, which usually supports heavy but slowly rotating or swinging load. It is usually a horizontal platform, such as the windward platform of traditional crane, slewing stacker or horizontal shaft windmill.

Slewing bearing
Compared with other rolling element bearings, the section of slewing bearing is thinner, and the diameter is usually one meter or more.
LDB slewing ring is usually made of gear teeth integrated with the inner ring or outer ring, which is used to drive the platform relative to the base.
As a professional slewing ring supplier, we provide high-performance small and large slewing rings.

Wind Turbine Bearings Market

/in /by

According to the 2022 “Wind Turbine Bearings Market” research report, investment in the wind bearing industry is moving towards high quality, high quality and process, focusing on the development of unique wind turbines, and construction begins on the sea and the sea.

wind-bearings
Bearings in wind turbines have different designs, the most common design combination of CRB\TRB and rolling bearings, to meet different market needs.
In the application of wind turbine bearings, one of the selected bearings is a larger bearing, which has a longer service life and greater friction, which reduces the power generation efficiency of the turbine. Bearings currently in use are too costly to replace, and we need to be stronger than today’s bearing technology and stronger and more durable than existing materials.slewing berarings
Bearings of wind turbines are the focus of this research. When the bearing is working, it must bear the pressure in the movement, and can maintain a good internal movement effect.
According to the survey, the new wind turbine bearings are stronger and more efficient. The global wind turbine bearing market is expected to reach USD 9.6 billion in 2024. The next generation of wind turbines is cheaper, more powerful, and lasts longer. The widespread use of new bearings makes turbine equipment an optimal choice for renewable energy generation.
