Bronze Powder Composite Split Bushing Self-Lubricating is a highly effective and innovative solution for industrial applications that require smooth and efficient operation. The bronze powder composite material, combined with the split bushing design, offers exceptional wear resistance and self-lubricating properties.
The bronze powder composite material is known for its durability and corrosion resistance, ensuring reliable performance even in harsh environments. The split bushing design allows for easy installation and removal, reducing downtime and simplifying maintenance tasks.
The self-lubricating feature of these bushings eliminates the need for regular lubrication, further enhancing the efficiency of the system. This not only reduces maintenance costs but also prevents potential lubrication-related issues such as leaks or contamination.
Wh used in pumps, motors, or other rotating machinery, Bronze Powder Composite Split Bushing Self-Lubricating offers a robust and reliable solution for ensuring smooth and efficient operation. Its unique combination of material and design ensures long-lasting performance and reduced wear, making it an excellent choice for industrial applications that demand high performance and durability.

METRIC BEARING POM BUSHES WITH OIL HOLES.pdf
The POM-based sleeve bearing, also called POM bushing, boundary lubricated bearing, oil-free bearing, dry bearing, POM bearing and POM coated dry sleeve. It has a similar material structure to dowels. The difference lies in the POM coated layer.
Yellow POM composite bushing is a standard item of our company. This type of self-lubricating bearing has the same material structure with other POM bushings.
1. POM 0.3~0.5mm.
2. Porous bronze 0.2~0.3mm.
3. Steel backing 0.4~2.2mm.
4. Copper plating 0.008mm.
