We are experts in tribology testing and understanding. Our expertise allows us to determine lubricant and chemical effects in tribology testing to aid product development.
We have experience in the following standardised and non-standardised lubricant tests:
Standardised Test Procedures
- FZG Scuffing (DIN 51354 Part 1, ASTM D-5182)
- FZG Micropitting (FVA 54)
- FZG pitting
- Dynamic seals
- Slideways – stick-slip and MWF compatibility testing
- Bosch Rexroth RFT-APU-CL
- Ortlinghaus clutch test
- Four ball weld (DIN 51350, ASTM D-2783)
- Four ball wear( DIN 51350, ASTM D-4172)
- Brugger (DIN 51347)
- Timken (DIN 51434, ASTM D-2782)

Custom rigs/modified rigs
We are able to support our clients in the specification, design and commissioning of specialist test rigs.
Failure Mode Identification
We have experience identifying lubricant and non-lubricant related machine element failures. Including those found in gears, bearings and seals:
- Micropitting
- Pitting/Spalling
- Scuffing
- Smearing
- Adhesion
- Abrasion
- Corrosion
- Polishing
- White etching Cracks
- Coating delamination
- High voltage arcing
- ESD (in filters)
Surface and subsurface analysis
We have expertise in surface analysis and are able to use this to identify and rate surface related chemical effects. We have experience using subsurface analysis to find and quantify inclusions and cracks in steels.
Lubricants and lubricant additives
We are experts in lubricants and lubricant formulation, including:
- Base oils
- Antiwear
- Antioxidant
- Detergents
- Dispersants
- Friction modifiers
- Corrosion inhibitor
- Extreme pressure agent
- Antifoam
- Viscosity index improvers/viscosity modifiers
- Seal swell agents
Reference oil formulation
We are able to select or formulate reliable and consistent reference oils. These are important for the development of any new standard or screening tests.
