Freudenberg Sealing Technologies (Plymouth, MI) has expanded its LESS (Low Emission Sealing Solution) lineup to include new products designed to address challenges associated with powertrain friction, smaller spaces, lighter weight vehicles and growth in the electric mobility vehicle arena. Covering the engine, transmissions and electric mobility product groups, the LESS portfolio was developed to focus on four core areas: emissions, friction, weight reduction and downsizing. One of the products in the portfolio suitable for the reduction of emissions and friction is the gas-lubricated mechanical face seal Levitex (pictured), which lowers CO₂ emissions by up to 1 g of CO₂ per km during driving, says the company. The Levitex seal also promotes a longer operating life by reducing powertrain wear. The seal's greater pressure stability is assisting with new developments in engine technology. According to Freudenberg, a German manufacturer has selected Levitex for its first series production order. For more information, visit www.fst.com .
