According to the study, ‘GLOBAL MAGNET BEARING MARKET RESEARCH REPORT:
FORECAST TO 2023’, major players in the magnetic
manufacturing market are Calnetix Technologies (U.S.), Siemens AG (Germany), Waukesha
Bearings Corporation (U.S.), Mecos AG (Switzerland), Foshan Genesis (China),
Synchrony (U.S.), SKF AB (Sweden), Celeroton AG (Switzerland), Schaffer AG
(Germany)
In the age of environmental consciousness, companies
operating across different industries are trying to build and use machines that
have no negative consequences on the environment. In a fit to achieve this
objective, companies are rediscovering fundamental principles of physics
–magnetic bearings. Magnetic bearings have multiple benefits and these include
reduced friction, minimized vibration and enhanced reliability plus the ability
to monitor and diagnose. All these are present without the disadvantages
associated with lubricants. The basic principle behind magnetic bearing is
magnetic levitation that is used to support heavy loads. There are various
types of magnetic bearings. One of them is passive magnetic bearings which do
not require any power source but are relatively difficult to design when
compared to active magnetic bearings which require a control system to monitor
the load as well as a continuous power source. One of the key drivers is of the
magnetic bearing industry is their increasing use in aerospace and defense
industry because of the cost efficiency these magnetic bearings possess.
There have been many developments in the
magnetic bearing market. Traditionally, the magnetic bearings were very
expensive but due to manufacturing advances that involved integration and
standardization of the bearings in the device, the overall cost has reduced
significantly. The engineering effort has also been greatly reduced. All these
factors have resulted in the magnetic bearings to become more economical.
Recent developments have resulted in the overall reduction in the physical size
of the bearing by nearly one third. Increasing the amount of steel in the bore
whilst simultaneously reducing the steel in the overall body has greatly
completed in achieving a reduced size. The length of the radial magnetic
bearing has also been reduced. The magnetic bearing also consists of a
controller the original size of which was that equal to a refrigerator.
However, with recent trends and developments this size now has been reduced to
that of a Laptop. Recent technology has allowed the remote to be integrated
along with the bearing itself which eliminates the need for a separate remote. On
the basis of speed, the market is classified into three segments. These include
up to 50,000 RPM, 50,000 RPM to 100,000 RPM and 100,000 RPM & above. The
market is dominated by bearings having a maximum speed of 50,000 RPM which are
used many end users for multiple uses. Speaking in terms of geography, Asia –
Pacific is expected to show the highest growth rate because of number of
humongous construction projects and increasing foreign investments in the
region.
With the advancements in technology, magnetic bearings today
offer got a greater number of machines and applications. Innovations related to
design that relate to miniaturization, standardization and integration have
resulted in greater usage of magnetic bearings for many existing and new
machinery products. The growth in this sector would also be complemented by
rising concerns over environmental degradation.
