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.

Water resistant grease: composition and applications

"Water compatibility of lubricating greases"

The search for the right lubricating grease for your business revolves around one critical consideration: what will its application scope be?

Greases are used for the lubrication and protection of mechanical parts as an alternative to or as a substitute for liquid lubricants, but as they are "pseudo-plastic" fluids, it is very important to study their characteristics well to be sure to have a proper water-resistant grease.

Compatible oxygen grease: when and why to use it?

Oxygen is present in the air, in diatomic form, in concentrations that fluctuate at around 20%. We also know that oxygen is one of the fundamental elements of the combustion process and that it can cause explosions or fires.

In many industrial processes, the isolation and control of the concentration of this chemical element requires some fundamental precautions both for the success of the process itself and for the safety of the plants. Let's look at the role of oxygen-compatible lubricating greases.

Rotary shock absorbers: how to increase the coefficient of friction

"More friction on your shock absorbers!"

Rotary shock absorbers are small but very precious components, which allow you to control the deceleration of rotary or linear movements, such as the opening and closing of glove boxes on the front passenger side of your car. To function properly, these shock absorbers need specific lubricants.

Pneumatic valves: operation and role of a good lubricant

"How do pneumatic valves work?"

Pneumatic valves are devices used for the control of actuators and for the regulation of the flow and pressure of compressed air.

Due to the numerous areas of application and the different stresses to which they are subjected, the correct lubrication of pneumatic valves is very important, especially with regard to sliding friction.

Galvanic corrosion: what it is and how to stop it?

Counteracting galvanic corrosion

Galvanic corrosion is a wet corrosion process that originates from any pair of different metals, sufficiently distant in the electrochemical series, placed in direct contact with each other.

The contact between a more noble metal and a less noble one creates a galvanic coupling, with the less noble metal that will be subject to corrosion, while the more noble one will remain intact.

Why is it called such?

Lubricating oils and greases: when to use one or the other

Oils or grease? Here is when to use them ...

Regardless of its complexity and structure, any mechanical system requires constant lubrication to maintain a proper functioning over time.

This lubrication can be ensured by products of different nature and composition, which vary depending on the mechanism itself, the functionality and the application context.

Every type of lubricant, oils and greases, synthetic or natural, has the same common goal:maintain the operation of the mechanism at high levels and extend its duration.

Their contribution to the life and functionality of a mechanical organ is often underestimated but if we told you that choosing the right lubricant for your machinery could increase its efficiency and durability by up to 30%, what would you do?

Dynamic rubber O-rings: which lubricants to use?

O-ring with dynamic seal and friction force

Compared to the static varieties, dynamic rubber O-rings are subjected to a higher mechanical stress. Since they are inserted between 2 moving parts, the risk of wear is far greater. Choosing the right lubricant is thus even more important.
