Bronze Cylindrical Bushing with Grease Groove

This straight sleeve is made of aluminum bronze alloy as the base material. According to customer requirements, oil grooves are machined on its surface. When the shaft rotates, the lubricating oil forms an oil film pressure in the wedge-shaped gap between the sleeve and the shaft. This pressure lifts the shaft, achieving liquid friction, thereby reducing wear, enhancing lubrication performance, and prolonging service life. It has excellent wear resistance and high strength, and is widely used in various mechanical equipment to ensure stable operation under heavy load conditions. 
High strength and excellent wear resistance: Tensile strength ≥ 540 MPa, yield strength ≥ 240 MPa, elongation rate ≥ 15%. It performs well under heavy load and impact conditions.
Excellent thermal conductivity: Thermal conductivity as high as 58 W/(m·K), with outstanding thermal conductivity performance, and can operate stably in high-temperature environments.
High-temperature performance: Melting point between 1040 - 1080°C, suitable for high-temperature applications, without deformation or damage.
Good impact toughness: Impact toughness ≥ 60 J/cm², ensuring the durability of the sleeve under impact loads.
Environmentally friendly high-performance material: Made of ZCuAl10Fe3 alloy, in line with environmental standards, and with excellent mechanical properties and service life.
