T
he OEM won the order from a local specialist in the design
and supply of equipment to the metallurgical industry. What
made it such a unique project for the company was the low
ambient temperatures that had to be accommodated according to
the specification.
These industrial gear units for mixing and agitating applications
require high torque ratings and function under a wide temperature
range. They feature a modular design with a specific housing concept
to ensure an optimal solution for diverse applications.
The low ambient temperatures in Kazakhstan meant that special
oil tanks with heaters had to be fitted to the units. While this is avail-
able as a standard feature, it is not a run-of-the-mill requirement.
Other features that had to be installed as well included flow switches.
The required loads of the application, which are considerable in terms
of agitators, had to be met.
The MC Series of industrial gear units comprises particularly
compact helical and helical-bevel gear units. The torque range of
the seven sizes is 6 kNm to 65 kNm. The parallel shaft design offers
plenty of flexibility in system design, in addition to requiring remark-
ably little space. This makes it ideal for a range of applications, from
materials handling to transporting heavy loads, mixing, crane drives,
and shredders. A version with Extended Bearing Distance (EBD) and
reinforced output shaft is also available for more specific applications.
The collaboration with the client in fulfilling this order for Kazakh-
stan represents a latest trend in the increasing internationalisation
of projects. It sends a positive message about the manufacturing
experience and expertise of this company, which is increasingly
sought-after the world over.
The MC Series is designed for a small torque range of up to 65
kNm, with special features such as limited space requirements and
high availability. The gear units are suitable for horizontal, vertical,
and upright mounting on the customer’s machine. The MC series is
particularly suited for medium gear ratios.
The modular concept includes a great variety of optional ac-
cessories, including motor adaptors, belt drives, and backstops.
Standardised applications solutions are available for bucket elevators,
cooling towers, and agitators. The company’s EBD concept allows for
stronger bearings within the gear unit itself, whichmeans that inmany

The Republic of Kazakhstan is the
world's largest landlocked country by
land area, bigger than all of Western
Europe. The country reportedly
holds the second-largest uranium,
chromium, lead, and zinc reserves, as
well as the third largest manganese
deposits, and is number five globally
in terms of copper reserves. The
country is also said to rank in the top
ten for iron and gold, and is a well-
known diamond exporter. It also has
the 11
th
largest proven reserves of
both petroleum and natural gas.
One of the largest orders in the history of SEW-EURODRIVE South Africa for its MC Series industrial gear units for a gold-mining project in
Kazakhstan, will see the assembly and supply of 31 of these units.
take note
• Kazakhstan represents an important mining market for this
company as it tackles projects outside its borders.
• The low ambient temperatures in Kazakhstan had to be
accommodated for this project.
• For this type of project, it is important that customer-specific
applications and tailor-made solutions can be provided.
