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%. As
a further benefit, service life with the new
grease is increased by a factor of 2.7.

NoTap
quick – clean - positive
A method for working on pressurised pipes
Traditionally, modifications to pipe systems
or repairs to leaking pipes or valves cause
major inconvenience or high cost. Often
these works involve draining down whole
buildings and lengthy refill with attendant
venting & de-aeration. Often the process
can take many days to complete and
re-commission.
NO TAP engineering goes to the heart of
the problem on pressurised pipe-work by
being effective in the right spot. It
eliminates drain downs, refilling and
venting. It accomplishes your solution in
an interval of time which other methods
fail to achieve.
It offers great advantages to the Contractor
and client alike – economy – no nuisance,
inconvenience or lengthy shut downs.
NO TAP – is quick – clean - positive. Work
is confined to where it is required.
