Wherever fluids are pumped, compressed or stirred,
it is the bearings and face seal rings that concern
design engineers in particular. The type of material
used for these parts has a vast impact on operational
reliability and durability, especially when critical
media are involved.
Due to their outstanding chemical and physical properties
as well as their homogeneous microstructure, our
high-performance ceramics have in many instances
displaced conventional materials. Their functional
reliability is the outcome of such factors as:
- high wear resistance
- corrosion resistance
- ability to withstand high temperatures and
- imperviousness to sudden fluctuations in temperature.
By mating aluminum oxides and silicon carbides we
are able to tune the sliding and sealing properties
very closely to the actual operating environment.
Combined bearings in high-performance ceramics are
remarkable for their lightness, stiffness, low
centrifugal forces and good emergency and dry running
