Corrosion resistant sintered bearings are usable bearings in environment where corrosion easily occurred such as in fuel or exhaust gas was developed.

• Low cost is realized by adopting aluminum bronze material, which is developed as the world’s first sintered bearings
• Excellent corrosion resistance compared to cupronickel material.
• Friction and anti-wear properties improved by optimizing the material composition.

Examples of use

• Fuel pumps
• Exhaust gas recirculation system

Test temperature : 35 ℃ / Salt concentration : 5% / Test time : 120h

Developed material	Cupronickel based material
Before the test → After the test	Before the test → After the test
No corrosion	corroded

→ Achieve the corrosion resistance equal or better than the over cupronickel.

PV value : 25MPa・m/min Test time : 1h

Wear resistance is cupronickel 9-times more than cupronickel

• Equal or better corrosion resistance
  No corrosion generated in JIS salt spray test
• Same 0.1 or less coefficient of friction
• 9-times or more wear resistance
