deva.bm^® installation by means of press-fitting

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

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.

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

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

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

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 ...

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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

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