THAT MOVES THE WORLD

Since 1759
250 years of exceptional engineering
GKN Sinter Metals Filters, the leading manufacturer of porous sinter metal products, offers a
variety of solutions to fulfil customer requirements.
We are familiar with various applications in almost every industrial branch.
Our products are applied in gas- and liquid filtration, dampening, sparging, sensor protection,
bulk handling and many more. We offer solutions for high temperature and corrosive
environments.
Sintered filter elements made of stainless steels, bronze, nickel based alloys, titanium and
several special alloys can be manufactured seamless up to 1,600 mm length and 320 mm OD.
Larger elements will be assembled in our certified in-house welding shop.
Our most innovative product for the chemical industry is the patented metallic membrane
SIKA-R…AS.
The filter cartridges equipped with this state-of-the-art technology offer a flow rate up to 4 times
higher compared to conventional sinter metal filter cartridges. Furthermore an excellent back
flush performance is guaranteed. The filter active membrane layer with filter grades down to 0.1
µm absolute has a thickness of only 200 µm and is made of the same alloy as the coarse support
material. The membrane is sinter bonded to the support and therefore cannot peel off.
Another innovation introduced by GKN is the sinter bonded joint of porous parts with solid
fittings in order to avoid welding seams – the weak spot of all sintered cartridges of our
competitors.
All sintered materials of GKN offer a self-supporting structure with high mechanical strength.
We manufacture various filter grades with specified pore sizes and flow rates in order to have
the appropriate solution for your requirements.

Properties of self-lubricating sintered
bearings
The properties of self lubricating bearings are
determined by the defined density of the bearing
material.
produced which forms a lubricating film on
thecontact surface and helps to circulate the
lubricant.
The resulting number of pores acts as a reservoir
for the lubricant.
In running condition, within a short time an
equilibrium is established in the circulation of the
lubricant.
Through linking of the pores, a canal system is

Applications
Various domestic appliances and hand
workshop tools…
… as well as usage in bigger machine
elements
Sintered self-lubricating sliding bearings are the ideal solution for applications where lubrication is
problematic or even impossible. The pores in the surface layer of a sintered self-lubricating bearing are
filled with lubricating oil making any further lubrication unnecessary.
The pore structure forms a labyrinth of interconnected pores of controlled size and volume, thus allowing
uniform lubrication over the entire bearing surface. The oil volume dispensed increases automatically with
the service temperature rising as a result of the increasing rotational speed.

Standard geometries of self-lubricating

Cylindrical bearing
Having the most economical bearing shape,
cylindrical bearings, for the most part, are pressfitted into a premachined housing with the help
of a fitting pin.

Flange bearing
Flange bearings differ from cylindrical bearings
due to the flange at one end.
E
The flange serves as a stop gauge in assembly
and, in certain cases, as an enlarged shoulder for
axial load. This shape of bearing also requires the
help of a fitting pin when press-fitted.
