High operating life deep groove ball bearing: optimized geometry
reduces friction, energy consumption and noise
50 percent less noise and 35 percent less friction - The
significant performance increase offered by this new bearing type
is primarily attributable to optimized osculation between the
rolling elements and ring raceways. Osculation between the balls
and rings has been optimized in order to minimize friction. The
improved surface structures of the raceways and balls reduce noise
development by 50 percent. In combination with improved surface
quality, the design measures reduce friction by up to 35 percent
compared with the previous deep groove ball bearing.
Other improvements include more effective seals and a riveted
steel cage. The innovative HRS seal ensures maximum reliability.
Its redesigned lip geometry is optimally adjusted to the recess on
the bearing inner ring. In this way, the seal offers more effective
protection against loss or contamination of grease. This results in
longer grease life and increases the life of the entire bearing.
The improved guidance of the rolling elements also contributes to
higher performance of the new deep groove ball bearing. The new
riveted steel cage offers higher rigidity and is therefore also
suited for higher speeds.
Altogether the design modifications result in higher efficiency
as well as higher achievable speeds and reduced noise. The benefits
are considerable increases in bearing life and performance with a
noticeable reduction in energy consumption. This new deep groove
ball bearing operates more quietly and efficiently, it is more
reliable and offers better performance than its predecessor.
