회사 소식 How to Choose the Right DU Bushing

What's DU Bushing?

Du bushing is a multi-layer composite sliding bearing designed to self lubricating, maintenance-free operation without the need for external lubrication. It belongs to the broader bushing family.

Du bushing is a cylindrical lining used to reduce friction, guide movement, or absorb vibration between two mechanical parts—most commonly between a shaft and a housing

DU Bushing Material Structure:

1. PTFE mixture:offers low friction and excellent wear resistance

2. Sintered bronze layer: improves load capacity and heat transfer

3. Steel back: provides structural strength

4. Copper or Tin plating : Help to anti-rusty

How does DU Bushing work?

• slide over rods or pipes, providing exceptionally low-friction motion.
• Their design excels at absorbing shock, which prolongs the lifespan of nearby machine parts and minimizes noise and vibrations.
• perform the same function but with the added benefit of retaining and reusing lubrication from the rod surfaces.
• By reusing this lubrication perpetually, the need for maintenance is drastically reduced.
