Mineral Oil vs Synthetic Oil: how to save by spending €300 per kg
During a meeting following a long period of consultation, the Purchasing Manager asked our Sales Representative, "Why should I use the synthetic lubricating grease you are offering me, which costs 50 times the one we are using now?" Our answer? "Thank you for your question!" Our Technical Sales Representative loves to be asked this, without irony. So, was the customer's question rhetorical or was it actually necessary to explain in detail what they were about to buy? The decision had already been technically approved but now it was necessary to summarise the results obtained and, above all, to quantify them economically. In this article, in addition to trying to resolve any lingering doubts, we will also look at:
Value for money of a mineral grease compared to a synthetic grease
We will do this with a crystalline example. We will compare the performance and the economic advantage that one of our customers has achieved by switching from the use of a lubricating grease composed of mineral oil costing €6 per kilogram, compared to a grease formulated with high-performance synthetic oil at €300 per kilogram.
We will tell the tale of a success story of a company specialising in the painting of frames for tractor cabs, belonging to a well-known industrial group. We will analyse the mechanical parts subject to high temperatures (180-190° C), to wear, friction and lubrication, comparing the results obtained with the lubricating grease in use and with the new solution proposed, tested, validated and adopted.

Counteract the oxidation of atmospheric metals with lubricants
Based on the ferrous material to be protected, the function of the component and the environmental conditions, the ideal anti-oxidation solution must respect specific characteristics and thus requires a precise formulation studied in detail.
Do you want to determine all the properties that a good lubricant must have to protect against oxidation? Download the guide and find out all the details.
Remedies against atmospheric oxidation
The oxidation of metals is the main enemy of the most common ferrous materials used for the manufacture of mechanical devices. It is an inevitable phenomenon but the effects can be reduced through appropriate measures during the production process and during transport, including the use of an anti-oxidation/anti-corrosion protective lubricants.

Plastic material compatibility: chemical sensitivity to lubricants
"Plastic friendly lubricant"
The compatibility of plastic materials - lubricant is a very current topic. Of course, the best way to reduce plastic waste is to optimize the use of the one already produced. On an industrial level this can translate into finding suitable (and tested) lubricants that reduce failures, deformations and excessive wear.

High-temperature grease: improve thermal resistance
Why use a high-temperature grease?
What happens to mechanical devices when they are subjected to high temperatures?
High operating temperatures can cause significant changes in the chemical/physical properties of the materials, resulting in greater wear, lower efficiency or poor performance in general.
Correct lubrication, rather, can inhibit such phenomena, so long as its formulation is studied in detail.

Plastic lubricant: compatibility with silicone greases
"Lubricants for plastic components"
The use of plastics in various industrial components continues to raise important reflections on the possible impoverishment of the structural properties of plastics due to the combined action of lubricant and mechanical-dynamic stress.
The destructive effects of the wrong plastic lubricant on your component can be immediate or, even worse, manifest after prolonged chemical action combined with mechanical stress, which means copious and almost always irreparable damage.
Silicone greases, for example, are lubricants that blend well with this material, increasing the life span of components and significantly improving their performance.

Food compatibility of lubricants
Food lubricants are those which, by their nature and composition, can be used in food production areas, where the risk of contact and contamination of the product (the food) is possible.
To be defined as such, however, it is necessary that the compatibility for food use is absolutely proven and certified according to strict standards.

How to optimise the operation of a gearmotor
Lubricants for gearmotors
Optimising the operation of a gearmotor means keeping it in perfect condition, through continuous and scheduled maintenance, careful checks on the component and adequate lubrication, both in qualitative and quantitative terms.

Lubricating oil viscosity: how does it change with temperature?
Lubricating oils and thermo-viscosity
Amongst the fundamental characteristics of a lubricating oil, viscosity represents the most important property, together with the chemical composition.
A lubricating oil, while promoting smoothness and protection from mechanical wear between two surfaces in reciprocal movement, introduces a friction whose value is closely related to its viscosity at a given operating temperature.

Creep Corrosion: Are your machines at risk?
No room for corrosion
Creep corrosion is a form of localised corrosion, which occurs in most cases near the coupling between two mechanical parts, in environments with high levels of humidity.
In practice, interstices are created in these coupling areas for reasons of dimensional tolerances, sufficient to trigger a mechanism capable of creating craters and caves in the components.
