• Easy to install and require less packaging space -- MicroTorq can be packaged in under 5 mm, further contributing to the design of compact, lightweight engines
• MicroTorq seals can be utilized without changing the design of any adjacent components
• Dynamic testing showed MicroTorq to generate approximately one-third-to-half the friction torque of conventional seal designs on average

Elastomeric Seal

Elastomeric seals offer a traditional design that leverages the fluid and temperature resistance and sealing characteristics of high-performance elastomers.

Federal-Mogul offers a full range of materials, from polyacrylates and ethylene acrylic to high-performance FKM compounds. The latter includes specialty FKM materials specifically formulated for today’s application conditions. Low-temperature FKM materials are capable of maintaining flexibility to -40° C, while base-resistant elastomers, including AFLAS®, can extend life in demanding applications.

Innovative design technologies, such as pumping lay-down lips and spring-loaded microlip seals, reduce running torque and extend the performance boundaries of these seals.

As light-vehicle life requirements increase, PTFE is increasingly used for these applications. Federal-Mogul’s patented lay-down sealing lip design ensures a long seal life despite extreme temperatures, aggressive oils, shaft imperfections, misalignment and excessive shaft motion.

In addition to a high level of chemical and temperature resistance and long seal performance life, our bonded seals also offer:

• More compact seal designs
• Simplified, single-piece structure

PTFE sealing technologies will operate at temperatures from -40° C to in excess of 200° C. They deliver superior performance levels with modern synthetic lubricants, enabling potential operation beyond 300,000 Kms.

Unitized (Cartridge) Seal

The unitized seal incorporates multiple seal components and functions into a single unit, bringing the management of the sealing interfaces together in one product. Benefits include:

• Reducing the level of shaft preparation
• Lowering the risk of installation error
• Reducing the possibility of handling damage
• Providing a complete sealing solution
• Improving sealing system reliability and durability

FLAT-INSTALL™ Seal

Federal-Mogul’s innovative FLAT-INSTALL seal is designed to perform under the extreme working conditions of commercial-vehicle/heavy-duty engines, as well as agricultural, construction and mine equipment, and marine and power-generation applications. This seal dramatically extends service life and reduces the customer’s total cost of ownership. It achieved a one-million-mile service life in simulated bench testing.

Other benefits:

• Non-contacting dirt labyrinth blocks contaminants from reaching and breaking down the sealing surface, dramatically extending seal life in dirty environments (e.g., construction, mining and agriculture)
• Integrated wear sleeve provides optimal seal surface to accommodate rougher crankshaft surfaces.
• Unitized design incorporating wear sleeve, seal and environmental shield simplifies installation and reduces risk of installation error.
• Design allows installation flush to the block without use of complex assembly tooling.
