Self-Lubricating Bearing 6mm 8mm ID Sleeve Sintered Bronze Bearing Bushings,sintered plain bearings are made of powder-metallurgical tin bronze, which has a large working temperature range from -80 degrees Celsius to 120 degrees Celsius.
Oil-impregnated bushings. - Direct from China
- As good frictional property as high sliding velocity, Oiled Bearing Sleeves have a small friction coefficient of about 0.12-0.18.
- Oil impregnation enables very high sliding velocity and makes them suitable for rotating applications.
- Uxcell sintered bronze bushings are most suitable for applications with rotating movements and where self-lubricating properties of the material are a prerequisite.

Lubrication
Most sintered bronze bearings are filled with oil. When storing and installing sintered bronze bearings, do not allow them to come into contact with absorbent materials that can draw oil from the bearings. No additional lubrication is required under normal conditions.
Main advantages of sintered bronze bearings
- Self-lubricating
- Maintenance-free
- High sliding velocities
- Low friction coefficient
- Low-noise running
Powder metallurgy process
1. First, the metal, in this case, bronze or bronze alloy, is transformed into powder. This can be achieved by a number of methods, including crushing, chemical decomposition and the most common atomization.
2. The metallic powder is then poured into a mold or mold cavity and compacted under great pressure in order to adhere the particles. This occurs at room temperature.
3. The metal part is then inserted into an oven where extreme heat melts the metal particles to form a rigid, porous and highly resistant component. This part of the process is called sintering.
The resulting porosity of sintered parts makes powdered metal products especially useful in lubrication applications and, as a result, bearings and wear plates are often made of sintered bronze. Powdered metal offers strength and flexibility. In addition, they offer an economical production process that includes oil impregnation or permanent lubrication.
