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.
◆ Key Features
● Lead-Free Construction – MG-2Y contains no lead, making it suitable for environmental compliance (RoHS) and applications where lead is unacceptable.
● Good Load Capacity and Anti-Wear – Designed for high load capacities and low speed with rotating, oscillating, or frequent stop-start motion.
● Extended Operation Without Relubrication – Can work for a long time without oil under boundary lubrication conditions when pre-lubricated with lubrication indents design. Periodic oil or grease lubrication will extend the working life span.
● Machinable POM Surface – The thicker POM layer allows for post-processing adjustment to achieve precise dimensions after installation.
● Good Corrosion Resistance – Plated coating (tin or copper) provides enhanced protection against corrosion in humid or chemically aggressive environments.
◆ 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
