IF YOUR MACHINERY DOES NOT HAVE CLEAN OIL YOU COULD BE THROWING MONEY AWAY WITH EACH PART
The cleanliness of the oil in your systems has a direct impact on your company.
The largest single controllable expense in a manufacturing plant is maintenance. Up to 80% of all machine failures are related to contaminated oil. The majority of this contamination comes from solid particles. These particles are even more dangerous when their clearance size is similar to or larger than that of the dynamic tolerance between the moving parts in your oil system. These particles flow with the oil in your system and find their way into fine clearances. The particles then become trapped in those areas and create micro cracks in the surface of the machine. The load and stress put on the machine then causes the crack to spread until the surface fails and more particles are created.
1. Particle Trapped
2. Cracking Initiated
3. Load and Stress Cracks spreads
4. Surface fails + created particles
The oil film thickness varies based on application. Hydraulic cylinders often have an oil film thickness of 0.5-50 microns. One micron equals .001 millimeters. To give some perspective, the naked human eye can see objects that are 40 microns or larger. While the human hair is 70 microns wide and a single grain of salt is only 100 microns. The level of precision in oil systems is crucial! The figure below shows different applications and their oil film thicknesses.

Something that we as humans rely on so heavily every single day can be causing serious damage to your system. Water. Without water, life would not exist. However, in your oil system water is the worst enemy. Due to the poor load capacity of water, as well as the lower viscocity, the lubricity of your oil is reduced. Just like hotsauce on your favorite breakfast spread, a little bit goes a long ways when water is introduced into an oil system. This is especially evident when water is put under high pressures found in load zones. The high pressure causes these water droplets to implode creating micro-pitting in the metal surfaces. As we know oil and water do not like to mix. This can lead to metal-to-metal contact where water vapors momentarily displace the oil.

Water acts as a catalyst to oil degradation, by causing oxidization while forming sludge and varnish in the oil. This harmful water can be dissolved, emulsified or free water. The amount of water that can be emulsified or dissolved in oil depends on many factors. The temperature, pressure, additive package, as well as the base oil all play a role. Most machine components require no emulsified or free water. This helps prevent against previously discussed micro-pitting, and oil degradation. Mineral based oils require less than 100 parts per million of water, or less than 0.01% water, to meet quality standards.
