The most desirable lubricative effect is to establish a durable boundary layer between the friction surfaces to prevent excessive wear in the event of an oil wedge break. Revolubes technology is aimed exactly at this goal, and to demonstrate it, we have conducted a simple experiment shown below:
Bearing roller test bench [Video].
A stationary bearing roller with a diameter of 9.5 [mm] is pressed against a rotating cylinder with increasing force, measured on a scale that is installed on a "quasi-falex" lever with a ratio of 10:1 — meaning that the actual force pressing the roller against the cylinder is 10 times greater than the force indicated by the scale.
The load increases until the lubricating oil film breaks, ultimately leading to the roller and the cylinder getting heat-welded together and causing the rotation to stop.
The bearing roller test allows for visual and quantitative comparison between lubricants by assessing the dimensions of the groove formed on the stationary roller for each tested lubricant.
On the other hand, the amperemeter connected to the electric engine clamps indirectly indicates the resistance the engine must overcome, thus the friction reduction for each tested lubricant.
- No lubricant
- Popular lubricant
As can be seen in the table above, Revolubes has a significant advantage over its test competitors. It preserved its lubrication wedge at a maximum force of 1500 [N] ~ 150 [kg], which could have been applied to the system by hand, and even then the rotation could not be stopped.
Moreover, the value of the friction force has not increased substantially, despite the significant load differences.
The ampere-meter, which indicates the value of current flowing to the electric motor driving the cylinder, indicated the value has increased slightly (about 1 [A]), despite a significant change in load - from 300 [N] to 1500 [N].
The groove was also significantly smaller, as illustrated in the pictures below.
Revolubes™ dry running properties.
Metal surfaces that undergo treatment with the chemically active formula of Revolubes™ exhibit remarkable characteristics for running without the need for lubrication. In the event of lubrication failure, such as line blockage or maintenance mistakes, the equipment will remain unharmed.
Dry running surface welding:
1. When two metal surfaces come into contact and are set in motion, there is a risk of collision due to their raised sections.
2. This contact generates a high "flash temperature" exceeding 1400 °C, resulting in the welding of the two tips.
3. However, as the metal surfaces continue to move against each other, the welded areas begin to break apart, causing damage to the surface. The particles from the breakout become suspended in the oil or grease between the metal surfaces, leading to additional harm. While larger particles are captured by particle filters, the smallest particles persist, gradually increasing the tolerance level.
Revolubes™ stops welding:
1. As mentioned above
2. Once again, the highest temperature arises when the two raised sections collide, posing a risk of welding.
3. This is precisely where the Revolubes™ molecule comes into play: It forms a chemical-physical bond to safeguard the two elevated areas. Rather than welding, it facilitates smoothing, thereby preserving the tolerance level.

Microscopic view on the rollers surfaces after the bearing roller test.
Clearly visible, the surface treated with Revolubes™ got smoothen and lacks welding marks, as opposed to its testing counterpart.
