DISCOVER THE SCIENCE OF FRICTION!

The base body represents the sliding bearing. In most sliding pairs, the base body is the wearing component.

Here you will find all relevant information on the installation of plain bearings by means of supercooling with nitrogen or dry ice. Shrinkage is discussed, as well as restrictions and limitations.

In our company, we attach great importance to the highest standards in the areas of quality, sustainability and safety.

Cleaning with residue-free, grease-dissolving agents (e.g. Loctite 7063) is permissible. Further information here.

The counter body or counter material is very often steel. In most sliding pairings, the counter body must not wear out.

The definition of a worn bearing depends on the type of plain bearing and the requirements from the application.

deva.bm^® is a bi-metallic material consisting of a steel strip as a supporting backing layer and a sintered self-lubricating bronze sliding layer.

With maintenance-free, self-lubricating high-performance sliding materials from the deva.metal^® product range, it is now possible to realize sliding bearing concepts that operate reliably over long periods of time.

deva.tex^® materials are suitable for applications with high, long-lasting static loads and for long friction paths.

Deva.ThrustSeal^® ND541 is a 2-layer composite sliding material with a sliding layer and an elastic second layer.

The dry-working sliding parts do not bind dirt and are therefore less sensitive to contamination than normally lubricated sliding parts.

Everything you need to know about the disposal of our plain bearings.

Dry lubrication improves the sliding properties of plain bearings, sealing elements and other machine elements.

Achieved by solid lubricants when insufficient lubrication occurs with grease or oil lubricants.

The friction or the coefficient of friction μ depends on the normal force. In polar friction pairings, the adhesive portion of the coefficient of friction is very high due to the attraction of the friction surface at low normal force.

Since 1970, we have been producing plain bearings with a polymer coatings, either with initial lubrication or without any lubricant at all. Our commitment to the environment extends not only to the manufacture of lead-free products, but also to environmentally friendly production.

Today's heavy-duty industry is driven by efficiency and effectiveness. But with the increasing awareness of our environment, it stands to reason that fat-free solutions are the right way to protect our nature.

The sliding partners are completely separated from each other by a liquid lubricating film.

The aim of this study is to define the COF and wear at different temperatures and to determine the effects between the quantity, size and distribution of the embedded lubricant.

If the base and mating body are made of the same material, this is referred to as an inherent pairing. Such friction pairings ...

In the past, lead was used to improve the metallic running properties. deva.metal^® materials were and still are partly produced with the addition of lead powder. New alloys are now being produced without lead. Lead is considered harmful to health. Furthermore, it causes a grain change in deva.metal^®. Read here.

Properly functioning lubrication places many demands on the design and the care of the user. Lubrication is often indispensable.

Maintenance-free plain bearings ensure independent lubrication, so that relubrication by hand is no longer necessary.

In the case of bearings with press-fit, the actual inner diameter of the bearing is only determined after mounting. Thin-walled bearings such as deva.bm^® or ...

Lubrication state in which partial solid friction exists alongside hydrodynamic lubrication.

The normal force acts at right angles to the friction surfaces and is part of Coulomb's law of friction.

Contemporary designs represent an enormous challenge for modern bearing materials. Under severe to extreme conditions as well as under the highest loads, maintenance-free is often expected.

Pipe and cable laying vessels play an important role in the emerging offshore wind farm industry. These various systems for pipe-laying vessels rely on the safe operation and long service life of self-lubricating and maintenance-free bearings.

PFAS ist eine Abkürzung für per- und polyfluorierte Chemikalien. PFAS kommen nicht natürlich vor und werden erst seit den späten 1940ern hergestellt und eingesetzt.

For an optimal maintenance-free sliding bearing system, the bearing pairing and the associated corrosion requirements are of high importance.

Yes, repair of dg plugs in deva.glide is possible.

Smoothing the surface roughness of new sliding pairs and forming a transfer film to reduce friction and wear.

The purpose of a bearing is to minimize friction as well as ensure wear-free and precise guidance of machine parts.

Because of their crystalline structure, solid lubricants are used when liquid (lubricating oil) or semi-solid lubricants (grease) fail.

Maintenance-free spherical plain bearings are becoming increasingly important in industrial applications. Increasingly high demands are being placed on machines and systems in terms of service life and maintenance. Self-lubricating spherical bearings from the DEVA^® system offer the best conditions for maintenance-free operation.

Occurs when the separating effect of the lubricant or transfer film (third body) is insufficient, as the initial friction is higher than the movement friction.

All information on how and where to best store Deva bearings.

The surface pressure results from the normal force divided by the projected contact area.

The transfer film, also known as the third body, forms during operation as a surface layer, in particular on the counter body but also on the base body.

According to Czichos, tribology is "an interdisciplinary field for optimizing mechanical technologies by reducing friction- and wear-related energy and material losses."

A tribological system essentially consists of a base body (sample) and a counter body (counter workpiece) sliding on it.

The wear rate (µm/km; material removal in µm per km of sliding distance) is often proportional or exponential to the normal load.

The current rapid development of wind turbines poses many challenges for suppliers, as the operating conditions of wind turbines are becoming more and more demanding. Therefore, turbine manufacturers need to use high-quality and reliable components. DEVA self-lubricating bearing materials best meet these requirements and offer maximum reliability for wind turbines.
