SF-2Y Non-Lead Boundary Lubrication BushingsSf-2 series
Material Structure
- Thickness 0.03-0.50mm, anti abrasion, low friction coefficient even without oil. The inside of the bearing are full of indentions, which need to be filled with grease before installing.
- Bronze power layer, 0.2-0.35mm, high load capacity and anti-abrasion, good thermal conductivity, which also further strengthen the combination of the POM layer and steel plate.
- Low carbon steel, which improves load capacity & thermal conductivity.
- Copper/tin plating layer, 0.002mm, anti-corrosion.
Application Characteristics
- Markedly superior performance to that of marginal lubricant materials present.
- Comparable embedment for foreign matters of babbit alloy.
- Suitable for high load, low speed with rotating oscillating motion.
- Hydro-resistant and don't swell up in the presence of moisture as other plastics does.
- A wear-resisting quality which is superior to all other slide-bearings in the presence of less lubricant.
- Suitable for oscillating movement, low speed with heavy load, frequent use and movements under load.
