Powerful and versatile
industrial gear units
SEW Eurodrive’s standard and
bespoke industrial gearboxes
are described by the company as
both powerful and versatile. The
heavy-duty X series range of helical
and bevel helical units offers a
choice of 23 finely graduated sizes,
with torque ratings from 6.8 to
475kNm.
This means that engineers can
select a gearbox that is exactly
right for their application, rather
than having to specify one that’s
too big because their requirement
falls in the middle of two size
options. Additionally, this ability to
make an optimal selection for every
task enables engineers to not only
cut cost but reduce weight as well.
Designed around a modular
concept, with the availability of
predefined accessories, the units
are infinitely flexible and adaptable
to suit a wide range of different
applications. The reversible gear
unit housing of the X series units
allows for variable installations with
a single version.
This means there is a reduced
number of variants for both
operators and original equipment
manufacturers alike. Other key
features of the X series includes,
operational safety, ease of
maintenance, extremely robust
gear unit housings, low noise
operation and efficient cooling
systems.
SEW Eurodrive’s IG (Industrial
Gearbox) range also includes the
MC, ML and MD series of helical
and bevel helical units with a
torque capacity of up to 2,584kNm.
The MC series offers compact units
designed for applications where
the space envelope is limited and
with lower torque requirements
up to 65kNm. The ML series is
for customer-specific applications
and tailor-made solutions for large
machines and systems with torque
up to 680kNm. The range also
includes the P and XP series of
planetary gearboxes with a torque
range of 24kNm – 6,000kNm.
The company is well known for its
short delivery times on standard
items and spare parts, and in
line with this philosophy there is
a design and manufacturing plant
dedicated to industrial gears so
that even large, bespoke units can
be designed and manufactured
quickly.
Applications include use on
agitators and mixers, conveying
systems, bucket elevators,
shredders and disintegrators,
travel drives for cranes, crushers,
grinders, toaster drives, and
paper machine drives. The largest
industrial gearboxes the company
has manufactured were truly
colossal units weighing in at over
50 tonnes. All SEW Eurodrive’s
industrial gearboxes are ATEX
approved and its X series range
is certified to ATEX M2 for
underground, mining applications.

Next-generation plastic bearings,
energy chains and cables
Leading plastics specialist igus
UK held live demonstrations of
its maintenance-free range
of xiros linear bearings,
RX energy chains and
robolink humanoid
modular joint system on
its stand (1641) during
this year’s Midlands
Design & Manufacturing
Show co-located with
Medtec. Visitors to igus had
the opportunity of meeting the
polymer experts to learn how to
optimise processes and reduce
costs through innovative use of
plastic components.
Available in five standard igus
materials, the xiros range of
bearings is ideal for a variety
of applications, ranging from
medical equipment, pumps and
measurement machines, through
to transport and conveying
technology – particularly in the
industrial sectors of chemicals,
food, laboratory equipment and
packaging.
Lubricant and maintenance-free,
xiros polymer ball bearings can
endure temperatures of up to
+150°C, are highly corrosionresistant,
can be washed and
cleaned, are non-magnetic and
are light weight. The plastic
ball bearings have excellent
friction coefficients to give high
performance and long service life,
even in the most demanding of
applications. As a result, users
can make overall cost savings
compared to conventional metal
ball bearings.
Also on show was a range of the
company’s energy chains, including
the fully-enclosed RX energy tubes.
The igus RX range features smooth,
domed outer contours for maximum
… all’s well…
that ends well!
Last Issue(Issue 47), we reported;
‘Boxers bid farewell’ one of many
major charity events organised, yet
again by Russ Arrowsmith of Arrow
Engineering Components Limited.
The money raised from that
farewell, white collar boxing event
at the Willows, gained £14,800.
The final cheque was presented
to Salford City Red’s and Salford
Lad’s Club.
protection against debris and
chips accumulation, as
well as dust, dirt, oil,
high humidity levels
and temperature
extremes. The
RX e-tube is
particularly wellsuited
to short,
self-supporting
lengths such as
those found inside
machine tools. They
can be delivered directly to the
machine as ready-to-fit units,
known as readychains, assembled
to size and fitted with cables and
hoses, suitable connectors and
even including a new guide rail,
which enables users to reduce
assembly times and storage costs.
A complete modular system, the
igus robolink range of lightweight,
maintenance and corrosion-free
connection joints for humanoid
systems will also be on display.
Suitable for use in areas of
general lightweight construction,
handling, automation and camera
applications, robolink can be
configured and expanded to many
designs and saves cost because
there is no need for expensive
milling, cutting or intricate
assembly work.
The system is driven by wires
and four or five degree of
freedom systems can easily
be constructed by connecting
joints together. The systems
can even be supplied with
NEMA 17 or 23 stepper
motors in a housing unit.
