Oilless bushes, constructed from plugged graphite bronze, are a reliable and efficient choice for various industrial applications. These bushes are designed to operate without the need for external lubrication, greatly simplifying maintenance and reducing the risk of contamination.
The graphite inclusions within the bronze matrix provide excellent lubrication, ensuring smooth and reliable operation. This oilless design not only extends the service life of the bushes but also contributes to a more efficient and cost-effective operation.
Oilless bushes are available in both straight and flange types, offering flexibility and versatility in installation and application. The straight type bushes are suitable for straightforward insertion into holes or shafts, while the flange type bushes provide additional support and stability in high-load or high-vibration environments.
The high-quality materials used in the manufacturing process ensure the bushes' durability and performance. They can withstand heavy loads and extreme conditions, making them suitable for use in mining, construction, and other industries where durability and reliability are paramount.
In summary, oilless bushes made of plugged graphite bronze, available in straight and flange types, offer a reliable and efficient solution for various industrial applications. They eliminate the need for external lubrication, simplify maintenance, and provide excellent performance in demanding environments.
bronze CuZn25Al5Mn4Fe3 + Graphite plugs
The high strength copper alloy was used as the base material, and the holes were machined and filled with solid lubricant according to the working condition. High strength copper and gold provide high bearing capacity while solid lubricants can form low friction pairs. Under the condition of dry friction, we designed a layer of pre-lubrication film on the bearing surface to ensure that the solid lubricant can be transferred to the dual parts in the shortest time and form an effective solid lubrication film.
oilless bushes material is made of strong cast bronze based metal with special solid lubricants graphite embedded. The base metal with stands high load and the solid lubricants provide for self-lubrication ...
The so-called oil-free means that there is no need to add oil or less oil. The goal of our research is to ensure that the bearing can still perform well under such conditions and extend its service life as much as possible. Self-lubricating bearing is the basic working principle of solid lubricant on the surface of the bearing in the early operational stage due to the friction of ask each other to form a transfer film and coat the to eventually form solid lubrication film on the grinding parts to achieve the purpose of self lubrication, which partition the direct contact between the workpiece and good protection of grinding extend the service life of the bearing and artifacts.
Modern design is creating a huge demand for today's self-lubricating bearing materials. Even in severe extreme operating conditions and maximum load conditions maintenance free is required. With the continuous increase of cost requirements, enterprises have higher and higher requirements on the reliability of equipment and plant operation. Metal self - lubricating bearings can meet the requirements of maintenance - free and self - lubricating in long - term service conditions, which makes it possible to design a reliable long - term self - lubricating system. Metal type self-lubricating bearing materials can be widely used for rotating, swinging and linear reciprocating motion under high load and low speed conditions, and also suitable for occasions where traditional lubrication cannot be achieved or is prohibited, or for long-term and stable use under special conditions such as dust, impact load or irradiation.
