Our Industry Solutions

Mechanical and plant engineering

Mechanical and plant engineering as a classical engineering science is a highly innovative industry nowadays.

Alongside our customers, we face the many challenges of the future. Together, we design and build bearing solutions which support in developing and operating complex machinery and equipment.

The constant further development of the most modern processing technologies and the use of efficient materials ensure we are always able to supply our customers with the optimal type of bearing. This is what makes slewing bearings made by LONGWEI the perfect component for bearings in mechanical and plant engineering.

Packaging and filling machines

To securely transport products of all kinds, modern packaging machines are indispensable. They are used to pack the most varied of goods and liquids in many different variations and as special solutions, for example, as bottle and can fillers, sealing machines or film winders. Packaging machines must meet two main requirements: Both high throughput and low waste. Continuously rotating slewing bearings help with this: They minimise wear caused by the packaging process and ensure the machines attain a long service life.

Using sealing machines, containers of all sorts can be sealed in a fully automated, efficient and secure manner. Generally, the machines are integral parts of modern filling machines. Containers are moved to the individual stations on large rotating carousels and conveyor belts. Our slewing bearings ensure this operation runs smoothly.

Film winder

In packaging technology, products are protected for further processing or transportation using paper, film or fleece. Film winders, also called unwinders, are used here. With these, products of all shapes and sizes can be packed. Our slewing bearings ensure the safe and reliable turning of the rotation axis in these machines. Moreover, their low friction levels mean wear and tear is minimised. This ensures the film winder’s faultless and, thus, long-lasting operation.

They ensure disposal solutions are able to carry out their work reliably, and for the benefit of the environment.

Raw material extraction and processing

There are a number of steps and processes in both the extraction and processing of industrial raw materials. Specialist machines are used for this. They manage the extraction of minerals and raw materials, their handling, transportation, storage, and eventually their treatment, for example, the breaking, sifting or grinding.

Bearings made by LONGWEI  contribute to the technical advancement of raw materials treatment. The hard operational and environmental conditions require extremely robust bearings to ensure their further processing remains efficient.

Spoil pile and conveying equipment

Spoil pile and conveying engineering revolves around creating solutions for the conveying of bulk goods, such as coal, sand, ore or grains. Reliable and powerful bearings are an essential component here, since the conveying tends to take place under difficult weather conditions, and often in remote locations. Environmental influences, such as storms, earthquakes or extreme temperatures place high demands on bearings. This applies to the sealing system too. This must be considered during the design phase.

Ship loaders and ship unloaders are important in ensuring the effective, material-saving and dust-free transportation of bulk goods on the shipping route. Coal, ores, phosphate, sulphur and fertilisers, but also food, such as grains, are fed onto continuously operational conveyor belts, and transported on a cantilever by means of the ship’s open loading hatch. From there, the goods get to the ship’s cargo space either in free fall, via a downpipe, or a slide.

For the ship to be optimally filled, it has to be moved under the cantilever. Elaborate manoeuvring can, however, be avoided if the cantilever’s unloading system is movable. This is where slewing bearings made by LONGWEI  come into play.

Typical products


Continuous ship unloaders

Continuous unloading systems are increasingly entering into the medium-to-large capacity range for the effective, dust-free and almost silent unloading of coal, ores, phosphates, sulphur, fertilizers and other bulk material.


Silos are used for the storing and mixing of bulk goods. This includes cement, powdered limestone, plastic granulates and also animal feed. Generally, a silo is filled from above and emptied from below. When material is removed, the uniform flow and optimal distribution of the different filling layers is, therefore, important. This is achieved by screw conveyors and other mechanical equipment. They blend goods which are to be filled at different times. Slewing bearings made by LONGWEI  are used to achieve the continuous rotations necessary. Since they are durable and resistant to bulk goods, they are perfectly suited to be used in this way.
