OMC2 Technology from TUNAP:

Lubricant Efficiency on a New Level.

Demand for More Efficient Lubricant Solutions

Higher, faster, further. The demands on technical designs are constantly increasing. This also presents tribology and lubrication technology with the challenge of developing ever more efficient and comprehensive lubricant solutions.

Market requirements are changing against the background of rapid economic change, global competition and technological progress. A typical requirement is the further reduction of surface friction to increase energy efficiency and to optimize the smooth running of motion sequences - even at extreme temperatures and under enormous loads. A further increase in power density is also required. After all, technical designs should be as small and light as possible, as well as extremely powerful. TUNAP offers a comprehensive solution for these different requirements: the OMC2 additive technology (OMC: Organic Molybdenum Compound).

Application Advantages of the OMC2 Technology

Our OMC2 additive technology offers several advantages compared to conventional lubricants.

It enables a longer service life with less lubricant consumption. Lower frictional temperature ensures reduced energy consumption and helps to reduce environmental impact and make a sustainable contribution to CO2 reduction.

The lower maintenance and repair costs also increase machine availability. This in turn results in cost savings on disposal. The bottom line for users is significant cost and resource savings.

OMC2 Additive Technology

The OMC2 additive technology (organic molybdenum compound), is also known under the terms PD (Plastic Deformation) or SE (Surface Engineering). What exactly does this technology do and what are its advantages?

The active complex of the OMC2 additive technology changes the structure of metal surfaces through a special micro-smoothing effect. This results in several advantages:

  • The roughness of components is not rubbed off, instead they deform under load.
  • The pressure absorption capacity of the surfaces increases strongly.
  • In the micro range, flow smoothing occurs and thus friction losses and wear are significantly reduced.

Three-Phase Effect of OMC2 Technology

The stronger the pressure, the more effective the OMC2 technology: Under increasing load, the OMC2 components migrate into the metal surface and lead to the special micro-smoothing effect of the surface structure. Unevenness is smoothed and friction and wear of the components are extremely minimized. The following three diagrams illustrate how an OMC2 lubricant acts on a surface:

Bildung eines Schmierfilms

1. Formation of a lubricating film on the surfaces

Under pressure, the additive molecules of the OMC2 technology first attach themselves to the metal surface. A shear-stable and lubricating film is formed.

2. Compression of the surface protection layer

With increasing pressure, the metal surfaces deform and densify on the nanoscale. The surface roughness is reduced and an effective protective layer is created. The risk of wear is already significantly reduced and the surfaces glide past each other more smoothly.

3. OMC2 effect develops and surface smoothens

The OMC2 components migrate further into the metal and lead to the special smoothing effect of the surface structure. This process, also known as PD (plastic deformation) or SE (surface engineering), leads to a minimization of friction and wear of the components.

Increase of Contact Areas through OMC2 Technology

Without OMC2 technology, the contact area between two friction surfaces is significantly smaller due to surface roughness. Only the rough "peaks" of the surfaces touch each other (see "before", exemplary visualization left).

By using the OMC2 technology, sufficient lubricant films and a protective reaction layer are formed on the surfaces. The contact area increases and the loads are distributed evenly (see "after", exemplary visualization on the right).

Examples for the Use of the OMC2 Additive Technology


Large gear: Car

OMC2 lubricants offer special protection in vehicle manual transmissions: they ensure smoother engine running, lower working temperatures and reduced engine oil consumption; they reduce fuel consumption and increase engine performance.
E-Bike Kleingetriebe

Small transmission: E-Bike

The OMC2 technology ensures less friction between the gears in e-bike transmissions This allows energy to be saved in the battery, which enables longer ranges.

Chains: Forklift truck

OMC2 hinges make the joints of forklift chains smooth-running again: They loosen rusted or oxidized chain joints and lead to lower repair costs and increased machine availability.

Roller bearings: Corrugated board plant

OMC2 is also effective in the production of corrugated board: even under extreme loads, wear in the rolling bearing is reliably reduced, which reduces maintenance and repair costs.

Chain Test Bench

For OMC2 technology, we rely on high-quality raw materials, carefully matched formulations and continuous quality assurance. This enables us to meet the highest demands on lubricants.

In order to measure the efficiency of various lubricants on the chain and to provide verifiable data, we test them on our two-wheel chain test rig AU 01, among other things.

In addition to cadence, torque, power, gear ratio and speed, we particularly analyze the parameters of efficiency on our chain test stand. With the data obtained from these tests, lubricants can be developed that guarantee the highest performance quality.


      Test winner in German "BIKE" magazine: TUNAP Sports "Chain Oil Ultimate".

We can simulate special stages or entire bike races on our chain test rig and draw conclusions as to which lubricant formulation is best suited to the distance to be covered.

Our tests show that the coefficient of friction can be reduced by up to 30% by using OMC2 technology. What does this mean in concrete terms? In a bicycle race over 155 miles, this could result in a time advantage of one minute and 46 seconds.

The latest test by the German "BIKE" magazine confirms the quality of our OMC2 technology: In issue 11/2020, 18 chain lubricants were tested for the criteria lubricity, creep ability, corrosion protection, dirt adhesion and handling. Conclusion: The TUNAP Sports "Chain Oil Ultimate" achieved the best result and was thus declared the test winner.


It runs and runs and runs... With TUNGREASE OMC2-2 plus lubrication, the power tool runs perfectly even after 250 hours.

Power Tool in Long-Term Test

In this long-term test, a cordless percussion drill ran with two different greases in continuous operation: first with the reference grease, then with TUNGREASE OMC2-2 plus. The result was clear: with the reference lubricant, the device failed after only 82 hours of operation. With TUNGREASE OMC2-2 plus, the device ran for well over 250 hours.

TUNGREASE OMC2-2 plus reaches a stable low level of power consumption much faster. This is due in part to the fact that this formulation is "dynamically light", i.e. it offers low resistance and facilitates movement. The OMC2 additive technology also reduces friction and thus heat generation, energy consumption and wear.

This is proof that lubrication with TUNGREASE OMC2-2 plus allows significantly longer operating times per battery charge.


The tests on the FE8 test rig show that TUNGREASE OMC2-2 plus significantly reduces the frictional torque.

Roller Bearing Lubrication

The full potential of the OMC2 additive technology can also be demonstrated on the FE8 test rig for rolling bearing lubrication:

In a standard test procedure for the performance of greases in rolling bearings under realistic conditions, our TUNGREASE OMC2-2 plus shows significantly lower wear values than greases from common competitors.

The average frictional torque reduced by around 50 percent both at start and in steady state means considerable energy savings compared with conventional lubricants.
