Costantemente migliorate le
caratteristiche dei cuscinetti
Le caratteristiche dei cuscinetti FAG radiali rigidi
a sfere Generation C, con forte presenza
sul mercato già dal 2008, sono state costantemente
migliorate. In particolare, sono state
sviluppate due nuove soluzioni di tenuta,
mentre minore perdita di grasso e migliore
l In caratteristiche tecniche importanti, come riduzione al minimo dell’attrito e del rumore, i cuscinetti radiali
rigidi a sfere di Schaeffler si dimostrano assolutamente competitivi.
l Schaeffler’s standard deep grove ball bearings are a benchmark when it comes to relevant technical
characteristics, such as minimizing friction or noise.

A Broader Range of Deep Groove Ball Bearings
Improved product characteristics, a new logistics concept, and optimum value for money make
Schaeffler’s deep groove ball bearings even more interesting. These products are suitable for quite a
broad range of applications, such as electric motors, household appliances, pumps and fans, electric
power tools and two-wheel vehicles.
Higher investments in new production and
logistics capacities as well as improved
product characteristics are the requirements
that allowed Schaeffler to expand its standard
rolling bearing business with FAG Generation C
deep groove ball bearings.
In the months to come, Schaeffler will
gradually put new production lines into
operation at its location in Yinchuan, China,
and double its capacity in the respective highvolume
product series of FAG deep groove ball
bearings.
Electric motors, household appliances, pumps
and fans, electric power tools, and two-wheel
vehicles are the fields of application in which
FAG Generation C deep groove ball bearings
are most commonly used.

Bearings features subject to
continuous improvement
Ever since FAG Generation C deep groove ball
bearings were successfully established on the
market in 2008, their product characteristics
have been subject to continuous improvement.
In particular, two new sealing concepts have
been developed, while less grease loss and
better protection against contamination
extend the grease operating life and, thus, the
bearing’s operating life.
The new Z-type dust shield with its innovative
labyrinth seal helps to reduce the egress of
grease by 20%, and prevents contamination by
30% in comparison with the previous design.
The patented ELS lip seal, which is optionally
available, provides maximum sealing action
at low friction and is particularly suitable
for alternating axial loads, such as in wheel
bearings in motorcycles. The improved sealing
action, without any additional friction loss,
is due to the innovative lip shape that is
perfectly matched to the ring recess. What is
more, the recesses that have been shifted to
the interior of the bearing significantly improve
the bearing’s robustness during handling, for
example during mounting.
The high-quality of the balls and the noiseoptimized
cage mean that FAG Generation C
deep groove ball bearings run significantly
more quietly than conventional deep groove
ball bearings. In addition, optimized osculation
reduces friction. These characteristics can
be attributed to the numerous optimizations
to raceway parameters with regard to
roundness, waviness, roughness, and tighter
manufacturing tolerances. Reduced friction
also means lower energy costs during
operation.
