ADDINOL expert tip –
Tips from the manufacturer

Obtain clear, understandable expert knowledge and practical information on lubricants and their application - directly from the manufacturer.

Abrasive wear

Abrasive wear is also referred to as abrasion. In this process, one friction partner acts on another and, due to its surface unevenness, generates abrasion or material breakout on the counterpart.

ADDINOL cooler protection – premixed and approved

Besides reliable lubrication, heat exchange is decisive for safe operation of a gas engine. Only the use of a high-quality cooler protection agent guarantees the optimum heat exchange.

Additives

Additives are added to a product in order to impart certain properties to it or to weaken undesirable properties. They change the properties of lubricants through chemical and physical effects.

Adhesive wear

Adhesive wear is the result of the transfer of material from one surface to another and typically occurs in poorly lubricated sliding movements.

Ball bearing lubrication

Ball bearings are a form of rolling bearings in which one or two rows of balls serve as rolling elements. They are used for small to medium radial loads.

Cleaning and protection of entire systems

In the context of general maintenance and repair or chains, slide elements and roller systems, for fault-free operation we recommend regular system cleaning with the ADDINOL System Cleaner HT.

Difference engine oil transmission oil

The best-known lubricants used in a car are engine oils and transmission oils. They are used in different places in the car and fulfil different functions.

Flash point

The flash point for oil is the lowest temperature at which an oil sample develops sufficient vapours under specified conditions for the air-vapour mixture above the sample to ignite for the first time without continuing to burn afterwards.

Fully synthetic oil

Fully synthetic oils are artificially created lubricating oils which have improved oil properties compared to mineral oils. The fully synthetic oils are produced by chemical processes such as synthesis technologies or polymerisation.

Gear lubrication

Gear wheels are used in transmissions to transmit and convert certain speeds and torques. They consist of at least two shafts in which the gears mesh closely.

HC synthetic oil

The term HC synthetic oil refers to a base oil of a lubricant which is refined by the production process of hydrocracking. HC stands for Hydrocracking. HC synthetic oil is a highly refined mineral oil with a high purity level.

LSPI

The abbreviation LSPI stands for “Low Speed Pre Ignition”. LSPI describes a combustion problem in downsized petrol engines with direct injection.

Lubricants wind power plants

Gearboxes, bearings and hydraulic units of a wind turbine operate under high loads: Shocks and vibrations, changing wind speeds and also temperature fluctuations are the order of the day.

Neutralisation number

The neutralisation number is an index which indicates the content of acids or bases in lubricating oils. It is specified for industrial lubricants such as gear oils, hydraulic oils or chain oils.

Plain bearing lubrication

In a plain bearing, bearings and guides hold engine and machine parts that are moving relative to each other in firmly defined paths.

Pour point

The term pour point can also be described with flow point or the cold behaviour of oil. The pour point describes the temperature at which the oil is still fluid and applicable under defined test conditions.

Pressure lubrication

Pressure lubrication (also known as injection lubrication) is a form of lubrication that uses one or more pumps to deliver oil to the lubrication points.

Rolling bearing lubrication

Rolling bearings are used in many different machines. They are installed in clockworks, rolling mills, industrial plants, bicycles, cars or ships.

Semi-synthetic oil

Semi-synthetic oil is a mixture of synthetic oils and mineral oils. The proportion of synthetic oils from Group IV base oils and Group V base oils must be at least 10%.

Shear stability

Shear stability describes the property of an oil to resist the action of shear forces and the related mechanical destruction by breaking and tearing. It is the resistance to changes in viscosity.

Splash lubrication

The term splash lubrication refers to a lubrication method for primarily industrial gear units. At least the lower teeth of the gears are located in an oil reservoir.

TBN

The abbreviation TBN stands for the Total Base Number. The TBN indicates the amount of alkaline additives present in the oil. In this context experts also speak of the alkaline reserve of engine oil. It is described how much acid can be neutralized.

Tribology

Tribology is also referred to as the science of friction. It describes the science of surfaces acting on each other in relative movements. Typical elements of tribology are friction, wear and lubrication.

Viscosity

Viscosity describes the flow behaviour of a fluid or gas. It reflects the extent of the internal friction of particles in a liquid. Viscosity is one of the most important physical characteristics of a liquid.
