NEW NSK DEEP-GROOVE BALL BEARINGS FOR
ELECTRIC MOTORS BOOST ENERGY EFFICIENCY
The low energy consumption of electric drives
is an important target in many industrial
applications and rolling bearings can play a role
in delivering this ambition. NSK demonstrates
this effect with a new series of deep groove ball
bearings that generates up to 80% less energy
loss, a factor that has a positive effect on the
energy efficiency of electric motors.
Before this development, NSK conducted an
intensive investigation into the parameters
influencing the energy loss of bearings, drawing
a number of interesting conclusions.
As a result, the new bearing series uses new
grease that has been specially developed for
friction reduction, while the grease filling level
has also been optimised.
In comparison with a conventional deep groove
ball bearing, the new NSK high-efficiency
bearings demonstrate 60% less friction when
using a steel cage. If a plastic cage is used,
internal friction is reduced even further, by
almost 80%.
