◆ Introduction:
MG-2Y can work for a long time without oil in the condition of prelubricated with lubrication indents design. It is widely applied in metallurgy machinery, mining machinery, water conservancy machinery, automobile, building machinery, agriculture machinery, rolling steel industry etc.
◆ Material Structure
1. POM with fiber 0.3~0.5mm
2. Porous bronze 0.2~0.35mm
3. Steel backing 0.4~2.2mm
4. Plated coating: Tin plating 0.005mm or Copper plating 0.008mm

1. Good load capacity and anti-wear.
2. It is used in high load capacities and low speed with rotating, oscillating or frequent stop-start motion.
3. It can work for a long time without oil in the condition of boundary lubrication, but to oil or grease lubrication periodically, the working life span will become longer.
4. It is machinable for the thicker layer of POM.
5. The bushes can be applied in auto chassis, forging machines, metallurgicals, civil engineerings, power stations, strip rolling industries etc.
6. MG-2Y is widely used in the machine where lead is unacceptable.
