Parker Boosts Its Magnetics Technology Portfolio with $3.6 Billion Acquisition of LORD,
World's Biggest Supplier of Magneto-Rheological Fluids
With hundreds of thousands of systems in the field and over
110 patents related to fluid formulations, device design, control
algorithms and manufacturing methods, LORD stands as a
market leader for adaptive suspensions. It is the exclusive supplier of MR fluids to BWI for its MagneRide automotive primary
suspensions.

Motion control company Parker Hannifin is boosting its already
sizeable portfolio of magnetics products and technology with a
$3.67 billion acquisition of LORD Corporation. A major provider
of magnetic fluids as well as advanced adhesives and coatings
used in magnetics manufacturing, Lord is largely a materials
science company with an array of engineered materials products and stacks of patents.

In an MR suspension, controllable MR fluid replaces traditional
hydraulic fluid in each shock absorber. As sensors monitor
road and vehicle conditions, a controller modifies the damping
characteristics up to one thousand times per second. This enables dramatic improvements in both ride comfort and handling
and can be used to improve the driving characteristics of any
vehicle, from high-end sports cars, to sedans and SUVs. First
introduced in the 2002 model year, the system now appears on
more than a dozen models from a wide variety of OEMs, including Audi, Buick and Ferrari.

The deal closed October 29 as an all-cash transaction. Historically a pneumatics and hydraulics-oriented manufacturer
of fluid power products, over its more than 100 years in business Parker has added many electromechanical products to
its lineup. The new deal creates a combined organization with
strong materials science capabilities, with more electrification
and aerospace product offerings positioned to capitalize on
emerging trends such as electrification and light-weighting.
"We are excited about the opportunity to strengthen our technology portfolio by significantly bolstering our position in engineered materials," said Tom Williams, chairman and CEO of
Parker. "We welcome the talented LORD team who have built
a high performing business with strong product brands such as
Chemlok," said Andy Weeks, president of Parker's Engineered
Materials Group. "Going forward, we will work collaboratively to
integrate our businesses by leveraging the best ideas, capabilities and practices of both organizations."
LORD has been working with controllable fluids since the 1980s
and says it is presently the largest global supplier of commercial magneto-rheological (MR) fluids, much of its output used in
automotive suspension systems and tactile-feedback steering
systems.

MR fluid in shear mode
MR fluids also can be used in shear mode, with the fluid flowing
between two surfaces, as in a tactile feedback device, or in a
valve mode with fluid flowing through an orifice as in a damper,
which move relative to each other. In the absence of a magnetic
field applied across the gap the fluid occupies, the fluid flows
freely or allows free movement. Upon application of a magnetic
field, the particles align like chains with the direction of the field.

MR fluids consist of magnetic particles, typically iron, in a carrier fluid. They are depicted in the image above. In the presence
of a magnetic field, the micron-sized particles link and change
the fluid to a semi-solid in milliseconds. When the magnetic
field is removed, the fluid just as quickly reverts to its natural
free-flowing state. The degree to which the fluid changes to a
semi-solid is proportional to the strength of the magnetic field,
giving the fluid infinite controllability and precision. Key applications for their energy-dissipation capability are brakes, shocks
and dampers. Response time always is less than 5 milliseconds; however, exact time is dependent on device design.
The fluids are gray in color and redisperse easily with proper
agitation. The iron particles contained in the fluid are between 1
to 20 microns.
