Freudenberg-NOK Sealing Technologies Reduces Vehicle Friction Through its LESS
Portfolio of Products
Products address automotive trends including fuel economy, light weighting,
start-stop and electrification

PLYMOUTH, Mich., Oct. 29, 2013 /PRNewswire/ --Freudenberg Sealing
Technologies CEO Claus Mohlenkamp and Automotive President Torsten Maschke
introduced the company's Low Emission Sealing Solutions (LESS) initiative
during a press conference in Weinheim, Germany today, indicating that the
products will address multiple transportation industry challenges.
During the conference, Mohlenkamp discussed the ability of these unique
components to reduce friction in vehicle applications, thereby helping
manufacturers improve fuel economy and reduce emissions.
"As an automotive supplier, Freudenberg Sealing Technologies is dedicated to
developing products that can respond to the global mobility challenges of the
future," said Mohlenkamp. "Natural resources are finite and fast-growing
metropolises in Asia and South America need specific mobility concepts. Acting
responsibly means developing solutions for the post-oil era at full speed –
using natural resources but as sparingly and economically as possible. With
the idea that 'LESS is more,' Freudenberg Sealing Technologies is giving
environmentally-friendly, resource-conserving mobility a major push."
Freudenberg-NOK Sealing Technologies in the Americas has also begun to
introduce the LESS initiative. The initiative underscores Freudenberg's
commitment to helping its customers develop and engineer superior,
environmentally-sensitive transportation solutions for the future. The
company's material development capabilities and technology expertise, which
have led to breakthroughs like the LESS products, are also the foundation upon
which Freudenberg builds strong customer relationships.
"We will only reach sustained growth if we concentrate on 'less,'" Maschke
told reporters attending the conference. "We have aligned our innovation
strategy with those of our customers to support demanding product development
objectives that call for higher power and performance standards and lower
emissions and higher fuel economy."
Over the past two decades, auto manufacturers have faced engineering and
environmental challenges including global requirements to lower tailpipe
emissions and increase fuel economy standards, use lightweight materials,
introduce start-stop technology and pursue vehicle electrification. LESS
products offer tremendous potential in addressing these challenges. For
oThe company's gas-lubricated mechanical face seal, Levitex™, under
development and due for introduction in 2017, is nearly friction-free. A
cushion of air is created between the slide ring and a counter ring,
leading to a 90 percent reduction in friction compared to a conventional
crankshaft seal. This cuts CO[2 ]emissions during driving between 0.5 g
and 1.0 g of CO[2 ]per kilometer. A 1.0 g reduction in CO emissions is
the equivalent of approximately 0.2 mpg savings in gas for a vehicle rated
at a 33 mpg. The seal also facilitates longer operation by reducing wear.
oThe company's Energy Saving Seal (ESS™), for engine crankshafts and
camshafts as well as transmissions, combines the robust sealing interface
of a conventional polytetrafluoroethylene (PTFE) collar with the
friction-reducing properties of an elastomer seal. Friction is reduced by
40 percent compared with a conventional PTFE lip.
oThe CASCO™ cassette-type seal up to 70 percent greater energy savings
compared with conventional lip designs used in other engine seals. The
CASCO cassette-type seal generates a much lower friction due to the
advanced design of its "axial" sealing lip. CASCO seals performed and
successfully passed several bench tests reaching over 1 million miles.
Customer field tests confirmed this performance.
oThe company can offer a multi-pole encoder that can be combined with a
radial shaft seal, creating one component. The elastomer layer, which can
be magnetized and encoded with north and south poles, provides the engine
control module with precise information on the rotational speed and the
position of the crankshaft – an important criterion for start-stop
systems. This makes it possible to minimize installation space, weight and
The company is also working on many innovations in the area of lightweight
construction. For example, hydraulic accumulators are saving energy and weight
in transmissions. Automatic start-stop systems require high volume flow for
short periods. A hydraulic accumulator with a lightweight design covers peak
pressure in the short term. This means the hydraulic system can be designed
solely for average energy needs, and the drive train can be made smaller and
Freudenberg has been able to build its expertise in the area of lightweight
construction through its joint venture with the Schneegans Group. This
partnership has allowed the company to leverage Schneegans' expertise in two-
or multi-component injection molding. Examples of this technology include the
3D-form full-plastic tubes for oil dip sticks and oil filler necks. These
components allow the tight space in the engine compartment to be optimally
used. In the case of 2K plastic pump housings, seals can be injected directly
for oil and water circuits for added functional security. The same is true for
housings with seals integrated into their covers with a 2K design; they absorb
dynamic stresses and can provide tolerance compensation even during
significant temperature swings.
Freudenberg-NOK is also making a contribution to innovative solutions in
electric mobility via its radial shaft seal or Simmerring^® seal technology.
The input shaft in an electrically powered vehicle's axle drive can become
electrically charged, potentially damaging the transmission. A Simmerring with
an electrically conductive PTFE-graphite nonwoven material grounds the
electrical charge from the shaft to the housing, effectively eliminating the
threat of damage.
The automotive industry is a key business field for Freudenberg Sealing
Technologies, accounting for nearly 50 percent of revenue, with total revenue
at 1.7 billion euros worldwide. The replacement parts business is also
important for the company. The company is responding geographically to the
auto industry's shift from mature to new growth regions. For many years,
Freudenberg's partnership with NOK Corp. has given it a strong position in
China and Asia. The company is currently strengthening its presence in Brazil
