NSK bearings help bakery save
€9400 per annum
A large bakery has replaced
the type of bearings used in
its cake-cutting machines after
experiencing repeat failures on
the integral blade saw pulleys.
The switch to NSK Molded-
Oil bearings immediately
reduced maintenance costs and
increased productivity, leading
to total savings of approximately
€9400 a year.
NSK´s Molded-Oil bearings
(stainless steel variant) are
ideal for applications in food
and beverage plants. Not only
do they prevent the ingress of
contaminants such as water and
particulates, but no lubricant
can escape the bearing and
enter other parts of the machine,
where it could conceivably
contact food. Molded-Oil
bearings are equipped with
a proprietary oil-impregnated
material that consists of
lubricating oil and a polyolefin
resin with an affinity for oil. This
carrier material releases the
lubricant continuously over a
long period.

WEG presents decentralised low-power variable speed drives
WEG, a leading global manufacturer of motors
and drives, has launched a new member of the
MW500 series of variable speed drives (VSDs).
Designed for decentralised installation, the
MW500 VSDs are now available for operating
induction motors with low power in the range
of 370 to 550 W.
The MW500 supports both voltage vector
control (VVW) and V/f characteristic curve
control and offers a robust and durable
solution. The VSD can handle an overload of
150 per cent for 60 seconds every ten minutes
and can be deployed at ambient temperatures
— up to 40°C wall mounting or 50°C for motor
mounting.
A sturdy housing design with protection rating
IP66 or NEMA 4X allows the VSDs to be
mounted directly on the motor terminal box
or on the wall using an adapter plate. This
eliminates the need for a motor feed cable
and switch cabinet, allowing users to install the
MW500 close to the controlled motor, increasing
deployment flexibility.
More information on the MW500 series can
be found on the WEG website, along with a full
range of the company’s VSDs. To discover out
where to buy the MW500 series, please click
