The Oil Copper Sintered Bushing is made of high-density copper powder through a high-temperature sintering process. Its internal pores are uniform and the structure is tight. Subsequently, the sleeve is soaked in lubricating oil to make it self-lubricating. This product not only reduces friction during high-speed operation, but also significantly extends the service life of the equipment. Its self-lubricating properties allow it to maintain good operating conditions without external lubrication, making it an indispensable key component in modern industrial equipment.

Self-lubricating Bushings:
A Oil Copper Sintered Bushing is a metallic component with high porosity (20-25% in volume), impregnated with a mineral based lubricant oil (non FDA/NSF). The oil contained in the porosity provides a constant lubrication between bearing and shaft,so the system does not need any additional external lubricant. Self lubrication allows this type of sliding bushing to work under hydrodynamic conditions, resulting in a very low friction coefficient
Self-lubricating sintered bushings have some advantages compared to other types of dry sliding bushings:
- -Reliability. The constant oil presence eliminates the risk of seizure, and allows the bearing to work during thousands of hours without wear.
- -Economy. Maintenance-free,no need for lubricants.
- - Performance.Able to work under loads of up to 1.450 psi,and speeds up to 0,2 in/s. The maximum working PV is is the range of 30 psi-in/s. but it can be surpassed in special cases, The dimensional precision is very high (up to IT 5 in diameter),and produce extremely low noise

FAQ
Q: What distinguishes brass shoulder bushings from other types of bushings in terms of material composition?
A: Brass shoulder bushings are specifically crafted from high-quality brass, a copper-zinc alloy known for its exceptional durability and corrosion resistance. This material composition ensures longevity and reliability, making these bushings ideal for various applications where robust performance is essential.
Q: How does the inclusion of a shoulder feature in these bushings contribute to their functionality?
A: The shoulder feature in brass shoulder bushings serves a dual purpose. Firstly, it provides additional support and stability to the components being connected, ensuring proper alignment. Secondly, it acts as a stopper, preventing over-insertion or misalignment, which is crucial in applications where precise positioning is essential for optimal performance.
