FARAX®-Bearing-FE8

Standardized Test Rig for Lubricant and Bearing Evaluation

The FARAX®-Bearing-FE8 is a high-precision bearing test rig designed for evaluating lubricants and rolling bearings under defined tribological stress conditions. Developed in accordance with DIN 51819, the system enables the analysis of wear, friction, temperature behavior and endurance under axial load. FARAX-FE8 is available in two configurations:

  • FE8-M with spring pack loading
  • FE8-H with fully adjustable hydraulic loading

Both variants are suitable for single-station or multi-station setups.

Applications & Test Types

  • Wear and friction analysis of lubricating oils and greases

  • Long-term endurance tests under defined axial loads and temperatures

  • Material behavior of bearings and cages (brass, PA, steel)

  • Influence of lubrication concepts and additives

  • Comparative testing of lubricant formulations

  • Evaluation of standard bearings per DIN, VW, ZF, FAG

Features & Benefits

The FARAX®-FE8 platform allows precise and reproducible testing with the following highlights:

  • Axial load up to 100 kN, spring or hydraulic

  • Continuously adjustable test speed from 7.5 to 4500 rpm

  • Real-time monitoring of torque, speed, temperature, and friction coefficient

  • Compatible with FAG 81212, INA, SKF and other standard bearing types

  • Designed for controlled heating, insulation, and safe handling

Test Methods:

  • 1. Fatigue / Wear Tests

    • Load: 80 or 100 kN, Speed: 7.5 rpm, Duration: 80 h
    • Temperature: up to 200°C (customizable)

  • 2. FAG 2-Step Test

    • Bearing: INA 81212, 90 kN, 70°C, 75 rpm for up to 800 h

  • 3. VW Failure Test

    • 60 kN, 100°C, 750 rpm, 200 h

  • 4. ZF Pitting Test

    • 68 kN, 100°C, 300 rpm, up to 750 h
