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.
