Rokolub AD 268 increases the lubricating performance of oils and it is used as an AW/EP (anti-wear/extreme pressure) additive. It is a component of formulations with both mineral and synthetic oils (POE, PAO). Rokolub AD 268 is a particularly important anti-wear and extreme pressure additive used in the lubricants intended for heavy loads. Its application provides a significant reduction in friction between moving parts of machines, reducing frictional wear of their components. Moreover, in very difficult operating conditions that generate boundary friction, Rokolub AD 268 helps to prevent seizing of machines.

Properties and applications

Advantages of Rokolub AD 268:

  • improves the anti-wear properties of mineral and synthetic oils
  • interacts with other anti-seizing additives (phosphorus, sulphur, chlorine), which allows to obtain a good surface protection in sliding contact
  • unlike the widely used sulphated and chlorinated additives AW/EP, it does not cause corrosion or metal colouring
  • is compatible with a wide range of oil additives
  • it is safe for human health

Benefits of using the product:

  • obtaining oils with better anti-wear and anti-seizing properties, and extending the service life of the equipment
  • reduction of rust compared to oils containing commonly used additives AW/EP based on sulphur or chlorine
  • possible to be used in a package with other oil additives
  • increased safety during production and use of oils


  • industrial oils: hydraulic oils, compressor oils, turbine oils, gear oils;
  • industrial greases
  • metal wroking fluids
