HIGH SPEED LIP SEALS FOR E-AXLE

An e-axle integrates motor, gearing and power electronics into a compact, modular package. Because of the compact size it brings additional space in hybrid or pure electric vehicles.

Specially formulated PTFE lip seals combined with unique bi-directional seal design provide worry-free sealing for the most demanding electric drive unit (EDU) applications. Proven in-production, real-world OEM performance in extended exposure testing to high rotational speeds, heat, friction and various lubricant and other media formulations:

Test Type	Details	Results
High Speed Test	1000 hours @ 17K RPM	Zero Leakage
Reverse Test	100 minutes @ 5K RPM (after 500-hour high-speed test)	Zero leakage
Oil soak test	ATF and EV gearbox lubricant	No swelling , absorption or reaction

We offer a wide selection of PTFE lip seal material formulations as well as seal housing materials for wide freedom of design and exact application fit with minimal size, weight and complexity and cover a wide range of dimensions.
