SM-9 oil mix

SM-9 oil mix, TU 0253-001-49878493-2005 mod. 1–13

The SM-9 oil mix is intended for use in helicopter gearbox transmissions during the wintertime. Helicopter gearboxes are used to change the torque direction. As the input shaft rotates, its rotation speed does not change because identical gears are used. The shaft power changes due to friction losses; the rotational energy is converted into heat. Oil mixes, including the SM-9 oil mix, are used to lubricate propeller hinges, axle hinges, helicopter propeller bushings in operation both in winter and in summer. There are also off-season oil mixes with an operating temperature range from -50 to +60 °C. They are used as synthetic oil for a gearbox in the MI-2 and MI-8 helicopters and in the main gearbox of the heavy MI-26 helicopter.
