CDS bearing materials are rigid polymer composites that
have solid friction modifier encapsulated within matrix. Normal wear
at the bearing surface continually exposes new lubricated surfaces,
so CDS bearing materials are able to remain self-lubricating
throughout its bearing life.
CDS bearing materials have fuelled growth of
applications throughout all sectors of industry, providing many advantages
over metallic bearings. There are currently many grades, each with its
own particular chemical and physical properties designed to suit specific
requirements.
The followings are just a few of the advantages they have to offer over
traditional bearing materials:
-
Low coefficient of friction
CDS materials show outstanding dynamic frictional properties.
This allows for higher combinations of loads and speeds.
- High resistance to wear
CDS materials provide good wear resistance, resulting in
many times longer service life when compared with bronze. It is also
less affected by poor lubrication and dirty conditions.
-
Excellent resilience
Excellent capability to absorb high loading and impact
-
Low or free maintenance
-
High load-carrying capacity
CDS bearing materials have a greater load-carrying capacity
than many other types in common uses. This is largely due to their
high compressive strength derived from the orientation and nature
of the reinforcements.
-
Excellent abrasion resistance
CDS materials can be used in environments where abrasive
particles are present.
-
Accept misalignment
-
Good chemical resistance
-
Noise and vibration suppressing
characteristics
-
Reduced wear of mating surface
-
Light weight
Light weight (as much as 5 to 6 times lighter than steel) translates
into less energy consumption and has a cascading effect which reduce
weight, wear, cost, etc. of other components in a system.
-
Good dimensional stability
-
Freedom from interface welding
-
Design flexibility
CDS materials, unlike metals, can be tailored to give exacting
performance characteristics.
