ROLLER ON ROLLER TRIBOMETER

About the Roller on Roller Tribometer

Roller on roller features independently driven twin disc configuration offering rolling-sliding contacts with a wide range of contact pressures.

The roller on roller set up is widely accepted as a reliable precursor to FZG tests.

Being modular, multiple contact configurations like block on ring, ball on ring, conformal contacts are also possible, making it a truly multifunctional tribometer that can be used for evaluating materials and lubricants used in rolling element bearings, gears and rail-wheel applications.

Technical Specifications

• Upper specimen: Roller: 47 mm in diameter, 10 mm wide (flat and crowned roller). Test block: 6.35 x 6.35 x 6.35 mm
  
• Lower specimen: Roller: 47 mm in diameter, 10 mm wide (flat roller)
  
• Speed: 2 to 2000 rpm
• Normal load: 0.1 to 8 kN (automatic loading)
• Temperature: Up to 120 °C (lubricated conditions). Up to 700 °C (dry conditions)

Variable Contact Geometries

Multifunctional system capable of changing the test configuration from line contact (roller on roller) to area (pin on roller or block on roller) or point (ball on roller) contact. Along with the ease of operation, it helps to achieve high throughput research.

Application Examples

• Screening of lubricants for high load power transmission systems at different slip ratios (i.e. gear oils).
• Investigate the tribological behavior of lubricants and steel interaction up to 120°C.
• Study the role of material structure in its friction and wear resistance behavior.
• Rolling contact fatigue behavior of materials used in bearings and railway wheels. Read more about White Etching Layer: A Risk For High Speed Railways and Urban Metros.
• High-temperature tribology (up to 700°C) of materials used in metal forming.
