Lower Friction, Weight, and Emissions – The Freudenberg BlueSeal

Freudenberg-NOK Sealing Technologies has begun supplying innovative, lightweight radial shaft seals to a major Detroit-based vehicle manufacturer for installation on the V6 and V8 engines powering its newest pickup trucks and sport utility vehicles (SUVs).  Enter the Freudenberg BlueSeal.

The BlueSeal, part of Freudenberg’s award-winning Low Emission Sealing Solution (LESS) portfolio of engine, transmission and E-Mobility product solutions, provides significant weight, friction and installation advantages over traditional radial shaft seals. Under the contract, Freudenberg-NOK will produce more than 2 million BlueSeals annually. Production is expected to increase further to more than 4 million units annually with orders from additional customers.

40 percent lighter and 50 percent less space to install

From turbocharged engines and 10-speed transmissions topicture of blueseal electrified and electric vehicle systems, the propulsion technologies on display at the 2019 North American International Auto Show (NAIAS) offer evidence that fuel economy, emissions and performance are still top of mind with manufacturers and consumers alike. Freudenberg’s BlueSeal offers customers a way to help achieve better fuel economy and lower emissions in large displacement internal combustion and turbocharged engines. The BlueSeal is 40 percent lighter than conventional radial shaft seals and requires 50 percent less space to install.

“Vehicle manufacturers are looking at every possible way to increase fuel efficiency and reduce weight, especially in trucks, SUVs and turbo-charged performance vehicles,” said Jeff Nelson, vice president, Automotive Sales, Freudenberg-NOK. “Even the smallest components can have a dramatic impact on the function and efficiency of vehicle powertrains.”

The BlueSeal is made of a single material – a steel-reinforced Polytetrafluoroethylene (PTFE) – designed to withstand harsh engine fluids while providing an axial space reduction, which allows manufacturers to downsize the engine. The seal has a low-friction Power Optimized Polytetrafluoroethylene (POP®) lip design that insures smaller dissipation loss, reduces the temperature in the contact area between the seal and shaft and performs flawlessly under different engine conditions.

Dual product development strategy for the automotive industry

The BlueSeal increases durability through its perfect sealing behavior and has a higher resistance to pressure than traditional seal designs. Its R-Tight® technology results in near-zero air leaks during assembly tests, allowing manufacturers to isolate other potential leak paths in the system.

Freudenberg is pursuing a dual product development strategy that supports continued development of advanced materials and components for internal combustion powertrain applications while pursuing new technologies that address emerging challenges associated with alternate mobility options like lithium-ion batteries and fuel cells. The BlueSeal, like many of Freudenberg’s LESS products, offers system benefits in both arenas.

“The automotive industry is undergoing profound transmission and driveline changes,” Nelson said. “It is our job to provide customers with exceptional component solutions that address the needs of all mobility platforms regardless of the fuel they use. The need to harness energy effectively and efficiently is a common denominator across our development efforts.”

Vesconite for Transportation/Automotive Industries

Transportation / Automotive bushings require regular maintenance and greasing, and are prone to wear especially in wet or dirty conditions. Self-lubricating Vesconite and Vesconite Hilube eliminate the need for continual greasing and at the same time increases bushing life. Vesconite and Vesconite Hilube are tough and durable and perform well under the mechanical stress that occurs on vehicle suspension systems.

Rail container trailers fitted with Vesconite

Vesconite Pivot BushingsSouth Africa – Vesconite flanged pivot bushings have been successfully installed and used on container trailers at the national rail utility. The Vesconite bushes, with a flange of 205 mm diameter and a bore of 165 mm, were fitted to the walking beam center pivot bearing that equalizes component parts of the rear axle bogies. This heavy duty application required a material which had high load carrying capacity, low friction, high wear resistance and good dimensional stability. Vesconite, with all these characteristics, was used on the trailers that are used to transport 12-m-long general purpose containers.

FluoroXprene Reduces Emissions

One of the greatest challenges of the 21st century is the conversion to a resource-conserving, sustainable economy. With this in mind, Freudenberg Sealing Technologies is offering customers its FluoroXprene® family of materials to help contribute to this transformation. Originally developed for use in fuel lines, these materials have the potential for use in new, challenging applications thanks to their outstanding characteristics.FST FluoroXprene Automotive

FluoroXprene was developed to reduce the permeation of fuel vapors through the walls of fuel lines. This permeation makes a notable contribution to a vehicle’s hazardous emissions. But it is often overlooked when considering total emissions. FluoroXprene reduces the escape of fuel vapors through the walls of fuel hoses into the atmosphere, slashing them to a fraction of their usual amounts. And this is not just the case for standard fuels – alternative plant-based fuels such as E10 and E85 are also securely contained by FluoroXprene materials.

Lightweight Seals: Innovations With Added Value

Lightweight design has recently become a much more significant trend in the auto industry. Even with small components like seals, a great deal of weight can be saved. From Freudenberg’s standpoint, several forward-looking issues come together in these approaches.

In his office, Dr. Ted Duclos, the CTO of Freudenberg Sealing Technologies, is holding up a palm-sized plastic ring.  “I know that it seems very small and insignificant,” he said. “But components like this quickly add up to several kilograms of weight in an engine.” And weight is one of the factors getting special attention from the auto industry – for a range of very different reasons.

Duclos has just returned from the Lightweight Summit in Würzburg, an international gathering of more than 300 experts from industry and research. Specialized lectures, discussion panels and presentations focus on lightweight design in the auto industry and especially in electric mobility. “Lightweight design is a trend,” Duclos said. In the design of classic internal combustion engines because low weight reduces emissions. And for the future of the electric car because reduced weight increases the vehicle’s range. Or to put it another way, lightweight design is one of several trends that are now logically tied to one another.
