Corrosion resistance bearing can be use under the environment where prone to corrosion such as in fuel or exhaust gas.

• Achieved low cost with the world’s first sintered bearing using aluminum bronze.
• 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

→ Corrosion resistance is equal to or higher than that of cupronickel materials.

PV value : 25MPa・m/min Test time : 1h

→ Wear resistance is 9 times or more than cupronickel materials.

• Corrosion resistance is equal to or higher.
  No patina (rust) generated in JIS salt spray test.
• Friction coefficient is equivalent, 0.1 or less.
• Wear resistance is 9 times or more.
