2.Extended Industrial Applications of DU Bearings
An Overview
Bushing bearings, also known as dry bearings or DU bearings, belong to a Bushing series, and are a type of sliding bearing known for their excellent self-lubricating properties. These bearings are composed of multiple layers, collectively providing stable and maintenance-free operation.
Typically, DU bearings consist of a steel backing, a porous bronze layer, and a polytetrafluoroethylene (PTFE) lining. The steel backing provides structural strength and support to the bearing. The porous bronze layer acts as a solid matrix, helping to retain and distribute the lubricating material evenly. Lastly, the PTFE lining possesses a low-friction surface and self-lubricating properties.
One of the key advantages of DU bushing is their self-lubricating property. The polytetrafluoroethylene (PTFE) lining acts as a solid lubricant, reducing friction and wear between the bearing and the shaft. This self-lubricating characteristic eliminates the need for external lubrication, making DU bearings suitable for applications where maintenance and lubrication are challenging.
DU bushing offer several benefits. Firstly, they have a low coefficient of friction, resulting in reduced energy consumption and improved efficiency. Secondly, they exhibit excellent wear resistance, allowing them to withstand high loads and harsh operating conditions.
In summary, bushing bearings are sliding bearings with self-lubricating properties, characterized by low friction, high wear resistance, and maintenance-free operation. With their versatile applications and stable performance, Bushing bearings are highly favored in industries that prioritize efficiency, durability, and reduced maintenance requirements.
DU bearings are commonly used in fitness equipment components such as treadmill rollers and drive chain systems. If bearing-related issues are detected early, replacing them with bushing bearings can prevent component damage. The excellent self-lubricating properties of DU bearings significantly reduce maintenance costs for fitness equipment.
DU bearings are also frequently employed in automotive suspension systems, including suspension arms, support brackets, and linkages. The outstanding self-lubricating properties enable DU bearings to achieve long-lasting stable operation in automotive environments.
DU bearings find extensive use in equipment such as pneumatic cylinders and fans. These devices often operate under high pressure and high temperature conditions, and the wear resistance and self-lubricating properties of DU bushing allow them to withstand extreme working conditions.
DU bearings are widely applied in agricultural machinery and equipment. For example, they are used in harvesting machine knife bearings, seeders' wheel bearings, and more. These applications often require bearings with excellent wear resistance, and DU bushing can provide stable operation while reducing maintenance requirements.
