Modern industrial greases are substances that avoids deformation and frequent breakdowns of moving parts of mechanisms and machines.
Their purpose is to provide the longest possible period of equipment operation, high performance indicators, work without interruptions. Today, these high-tech compounds are extremely effective in protecting production mechanisms from wear, corrosion, scuffing, overheating and, as a result, deformation and frequent breakdowns.
Industrial greases are most commonly used in:
- connecting units of mechanisms;
- worm, cable and gear drives;
- rolling and sliding bearings;
- hinges and (brake) calipers.
It is in these places where mechanical parts experience maximum stress in the form of resistance and frictional force. To mitigate them and for full surface contact interaction, apply a thin layer of lubricant.
The lubricant can be:
In whatever form or consistency it is produced, its main purpose remains to protect the mechanical assembly, which includes:
- hydro and thermal stability;
- reduction of friction and wear, heat dissipation;
- resistance to alkaline and acidic environments;
- optimal degree of adhesion and tightness.
According to viscosity index, lubricants are semi-liquid, liquid, semi-solid, solid and even gaseous. Currently popular greases fall under category of semi-solid, because they change their state under certain temperature conditions and load, turning to liquid and providing an optimal degree of lubrication to parts. Meanwhile, their performance indicators are much higher than classical liquid ones.
Lubricating products come from petroleum oil. This is a constant element of such compound. In addition to oil, synthesized and organic components (oils) can be added.
Lubricants are conventionally divided into:
- Mineral (with a minimum degree of oil product purification).
- Semi-synthetic (synthetic products are included in the formula).
- Synthetic (with a fully synthesized components).
To improve the characteristics, special additives are also added to the lubricants. They provide increased protection of parts from heat, increased friction, oxidation, moisture, dust and solid particles and improve the duration of service.
