DEVA sel-lubricating bearingsin Marine and Oshore Applications
Today Federal-Mogul DEVA is valued worldwide as a particularly
prime address or maintenance-ree, sel-lubricating sliding bearings
ullling the highest standards in industrial applications. At our
location in Germany, we use state-o-the-art equipment to develop and
manuacture bearing systems rom 1 to 32,000 mm in diameter.
With our highly motivated team, we have one aim only: to constantly
rearm the satisaction o our customers, thus ensuring steady growth
in demand or DEVA® products. Find more inormation in the Internet

Design, Reseach& Development
Investment or innovation
Oshore and Marine applications constantly require new bearing developments. Federal-MogulDEVA´s application engineers work on new bearing designs rom the initial inquiry to the nal design.
It might all start rom a preliminary inquiry speciying application details such as loads, speeds,
riction distance and other conditions, and maybe a required lietime. Based on this inormation a
suitable DEVA bearing material is chosen rom hundreds o options to meet the design requirements
or any particular application. The best results are usually achieved, i we work in close collaboration
with our customers.
Ater all, we at DEVA know our bearing materials better than anyone else. We know that they
suit the extreme Marine and Oshore demands because we have 70 years o experience o
manuacturing bearings.
DEVA´s R&D sta is constantly developing and even patenting new materials. In addition to that we
are able to perorm tests on dierent materials simulating a var iety o conditions according to the
application specications. Federal-Mogul DEVA uses unique and customized test rigs. We are not
only able to test bushings and plates applying dierent movements, loads and speeds, but also under
special conditions like extreme heat, dierent oils or sliding pastes, sea water and sand, sub-zero
temperatures and hydrodynamic lubrication, just to name a ew.
What are Your demands like? We at Federal-Mogul DEVA would like to know.

DEVA® calotte bearing for pivot points
The market or sel-lubricating and maintenance-ree bearings
is growing rapidly within the Marine and Oshore Industries.
Increasing maintenance cost, the pressure o competition and
the need to be environmentally riendly is leading companies to
change the way bearings have been used or decades: Grease
is substituted with solid lubricants which orm a lm with lowriction between the bearing and the mating part, thus separating
them rom each other. This allows a low and controlled wear
combined with low riction. Extreme operating conditions and
challenges like high loads, stick-slip, chemicals, edge load, dirt,
corrosion, small angular movements, extreme temperatures,
dicult or impossible lubrication among others are everyday
challenges or Federal-Mogul DEVA. A high-end sel-lubricat ing
bearing can be used as a solution or all these demands.
DEVA has a broad range o dierent maintenance-ree materials,
enabling a custom-made bearing solution or each application,
regardless o i submerged, above surace or in the splash zone.

deva.glide® materials consist o highly wear-resistant
copper cast alloys showing sliding suraces with
evenly provided solid lubricant plugs according to
the so-called “macro distribution“ principle. These
plugs are arranged according to the movement
requirements. The high density o the bronze ensures
high stability under load along with good dirt particle
embedding properties into the lubricant plugs.
Under dry running conditions, deva.glide® is supplied
with a 10 - 15 µm thick running-in lm which enables the
solid lubricant to be transerred to the mating material
at the rst contact between the sliding partners.
deva.glide®
allows maintenance-ree operation due to the solidlubricant content o the sliding material.

can also be used in applications involving additional,conventional lubrication.
available also as a thinwalled version.
deva.tex® is a sel-lubricating, glass-bre reinorced composite bearing material
which is produced using a special winding technology. The base material
ensures high strength, while the sliding layer contains special non-abrasive
bres and solid lubricants which ensure excellent tribological properties even
in damp environments or in the event o edge loads. The solid lubricants were
developed to give extremely low coecients o rict ion and wear rates in both
wet and dry-running conditions.
deva.tex®
is available as a precision cylindrical or spherical bushing with inner diametertolerances H8/D8/E8, or as a standard bushing with inner diameter toleranceD11. The required grade o precision depends on the application.
