FAG FE-8 and FE-9

FAG FE-8 – Wear protective properties

• DIN 51819
• Qualifying test for roller bearings
• Testing conditions
• • Type of bearing (angular contact bearing or tapered roller bearing
  • Rotational speed
  • Axial load
  • Temperature
• Output: Bearing temperature, friction and wear of the bearing components
• Technical data sheet information: For example roll 31312-75/50/RT: 22 mg

FAG FE-9 – Operating service life

• DIN 51821
• Determination of the operating service life of the lubricant at high temperatures
• 5 angular contact bearing at different temperature
• Failure criteria: excessive torque
• Output:: average operating service lifeF50
• Passed whenF50 > 100 h

Further operating service life test: SKF R2F
