Siemens approval for Eco Gear GLS
With the official approval of the Eco Gear GLS lubricant, Siemens Traction Gears is setting an important benchmark for the lubrication of its gearboxes. Eco Gear GLS 75 W 90 and GLS 75 W 110 are the first wheel set gearbox oils available in two SAE grades, enabling more efficient and flexible use in modern rail vehicles. Eco Gear GLS also impresses with its high performance, longer maintenance intervals and improved energy efficiency. It thus contributes to more economical and reliable operation.
The approval for Eco Gear GLS 75 W 90 and GLS 75 W 110 covers all Siemens wheel set gear types (formerly Flender T7302) and highlights both the technological innovation of Siemens Traction Gears and the high technological quality and reliability of ADDINOL lubricants. Thanks to their formulation tailored to wheel set gearboxes, ADDINOL Eco Gear GLS 75 W 90 and 75 W 110 ensure lower friction losses, reduced wear on the gearboxes and consistently high transmission performance in rail vehicles.

ADDINOL Eco Gear GLS 75 W 90 and GLS 75 W 110 are silicone-free, synthetic high-performance gear oils for wheel set and axle gearboxes in railway applications. They offer maximum load-bearing capacity at API GL-5 level, long-lasting wear and corrosion protection in a wide operating temperature range from -30 °C to +120 °C. At the same time, they have been proven to improve drive efficiency in both extremely cold and very high temperatures. They reduce operating and maintenance costs through significantly extended mileage and service life. The highperformance gear oils also impress under extreme loads and overloads with constant performance and low-noise power transmission – an advantage particularly in urban rail transport. Thanks to their optimised friction characteristics and stable lubricating film formation, they have been proven to reduce wear and increase the long-term operational reliability of the gearboxes.
Eco Gear GLS is approved by AS Drives, Siemens Traction Gears GmbH and Voith Turbo. Furthermore, ADDINOL has been audited and listed as Q1-certified by DB, ÖBB and SBB.
