In lubricated friction contacts, the lubricant functions as a machine element. The type of lubricant supply and the possibilities for influencing the lubrication state at the friction contact are thus central for model testing with adequate practical relevance. The SRV® test system allows the investigation of all types of lubricants. Liquid and pasty lubricants as well as bonded coatings are applied manually or with a pump.

  • SRV® can be used to investigate all lubricant types
  • Our technologies allow numerous simulation options
  • Fast results and accurate data for lubricant development

Practice-relevant and goal-oriented - the supply of liquid test media and influence of the lubrication condition

To produce different lubrication systems and lubrication conditions, we use several types of pumps to supply liquid test media. Our test system allows variable influence of the lubrication state. Circular lubrication, drip or splash lubrication or insufficient lubrication can be simulated. A series of specially designed, application-specific oil baths is used to collect the oil. Depending on the desired lubrication type, fresh or used oil can be permanently applied to the friction contact over two channels. The lubricant supply is controlled based on performance, and depending on pump type and application, either according to percentage or quantity.

Variable temperature control

Oil temperature and amount can be dynamically controlled for application-oriented simulation of the operating conditions of lubricated friction contacts. 


  • Counting wear particles in an oil circulation system with n-RAI
    A circulating lubrication system is used to measure nanowear with radioisotope technology. An oil pump creates a lubricant circuit between the friction contact and the measuring unit, which counts the wear particles in the lubricant flow. > Learn more
  • A-FA: Change the composition of liquid lubricants during testing and observe the effects of additions online
    The A-FA formulation assistant lets you add up to two substances to liquid media during testing. The newly developed formulation is then pumped into a lubricant circuit.> Learn more
  • Determine the lubrication state or existence of a lubricating film by measuring electrical resistance

    A dynamically controllable pump setup lets you vary the quantity of lubricant on the tribocontact during testing. By comparing the flow rate of the pump to the friction coefficient and electrical contact resistance values, you can identify an optimal lubrication situation or the minimum requirement for lubricant availability in the tribological system.

  • Investigate emergency running properties by dynamically controlling the amount of oil
    You can dynamically increase and decrease the lubricating film during the test via the quantity of the medium transported to the friction point.
