New Geometries
The superior material properties of BIOLOX ®
delta permit component geometries that
were not possible with previous ceramics.
Cup liners with thinner wall thickness still
are able to offer increased stability and
safety as they allow the use of ceramicon-ceramic
bearings in larger diameters.
In contrast to metal and polyethylene,
ceramic bearings with larger diameters
show no significantly increased rates of
wear.

Precise Lubrication Clearance
A further advantage to thin-walled ceramic
components results from the material’s
high stiffness. This ensures that the precisely
adjusted lubrication clearance between
the components, which is necessary
for the formation of a lubricating film, is
not compromised by any deformation in
the thin-walled elements.
Sizes and Material Combinations
Ball heads and cup liners made of BIOLOX ®
forte and BIOLOX ® delta can be combined
in bearings. Ball heads made of both materials
can also be combined with cup liners
made of polyethylene and highly crosslinked
polyethylene.
* The exterior diameters of the cup liners are adjusted to the interior
diameters of the various cup systems.
