Levitex – the frictionless revolution 

The engineers at Freudenberg Sealing Technologies have come very close to the vision of a frictionless seal: The Levitex crankshaft seal creates an air cushion that seals the engine compartment with virtually no friction. Levitex can thus reduce the CO2 emissions of vehicles by 0.5 to 1 gram per kilometer. And because less friction also means less wear, Levitex ensures a prolonged operating life expectancy.

OFTEN INVISIBLE.
ALWAYS ESSENTIAL.

"Our gas-lubricated Levitex mechanical seal is a revolution in sealing technology. The sliding surfaces run on a cushion of air, resulting in 90 percent fewer frictional losses than a conventional crankshaft seal. This allows us to reduce the CO2 emissions in driving operation by up to 1 gram per kilometer."

Eco-Friendly

The revolutionary Levitex seal reduces the power loss compared to a PTFE crankshaft seal by up to 90 percent. Mechanical friction no longer exists – only the shearing of the air creates a trace of resistance. The result: less fuel consumption, less wear, longer service life and CO2 emissions are reduced by up to 1 g/km.

Less wear and longer service life

Less is more: Levitex has no sealing lip which can wear out, and the sealing surfaces can never run dry. The revolutionary concept of Levitex consists of a stationary and a rotating unit. Both seals are provided with an extremely robust coating and withstand even the extreme challenge of Arizona dust. Temperatures between -40 and +150 °C cannot harm Levitex. And even the dreaded wading tests of OEMs, with water crossings and idleness in water, are passed without problems by Levitex.
