About Longwei
About US : The story of Longwei began in 2004, As the main technical director and one of the production workshop directors of Xuzhou Rote Eide Slewing Ring Manufacturing Co., Ltd., Mr. Zhao chose to leave due to the expiration of his labor contract and started his entrepreneurial career.
Our factory is located in Xuzhou City, Jiangsu Province, China, which is known as the capital of construction machinery in the world.
Due to the presence of XCMG, Caterpillar, and ThyssenKrupp Xuzhou Rothe Erde slewing-bearing companies, the region has gathered a large number of the world’s most outstanding talents, funds, and technology related to construction machinery and its accessories.
For 20 years, we have been committed to the R&D, design, manufacturing, and service of various slewing bearing products, LONGWEI is a professional slewing solution supplier with slewing bearing, The company has strong technical strength, strong production capacity, and complete testing equipment, enabling us to provide 2000 sets of slewing bearing per month.

Future-oriented product portfolio
The portfolio is continuously developed and improved so that the product portfolio is always state-of-the-art.
As broad as the areas of application of slewing bearings are, their individual designs are equally diverse.
As the leading manufacturer of slewing bearings, our aim is to create solutions and manufacture products that have an above average service life, even while being subjected to harsh operating conditions.
How Does a Slewing Bearing Work
A slewing bearing, also known as a slewing ring, is a machine element that absorbs all axial and radial forces and the resulting tilting moments, in a single, self-retaining and ready-to-install bearing unit.
The goal is to quickly and easily transfer the forces acting on the slewing bearing to the adjacent structural machine elements. The overall design of the product, including the inner and outer rings, the gear cutting, rolling elements and mounting holes, enables it to transmit the applied loads and allow smooth rotation at the same time while maintaining a compact footprint. Slewing bearings enable and facilitate the rotational motion of wind turbines, excavators, cranes and tunnel boring machines, just to name a few. The slewing bearing offers many advantages compared to other solutions, including taking up significantly less space, weighing less and being more cost-effective in most cases.
The Production Process –
How a Billet Steel is Turned into a Slewing Bearing
The challenge of the production process is to manufacture a product that can withstand the intended operating conditions over the long term. Among others, these are:
- Installation, also in extreme conditions, e.g. in offshore wind turbines.
- High axial and radial forces, e.g. in machines used in the construction industry and infrastructure development.
- Tilting moments, e.g. in large crane systems.
- Heavy loads, e.g. in transport and conveying technology.
