    Gear STR

    Premium Quality Industrial R&O Gear Oils
    PETRONAS Gear STR is a premium quality R&O industrial gear oil specially formulated for the lubrication of plain and anti-friction bearings, gears and crank mechanisms in which lubricants with extreme pressure (EP) and detergent properties are not required.
    It is manufactured from specially selected premium quality base oils for their oxidation stability and water separating characteristics, and further fortified with selected oxidation and corrosion inhibitors to ensure long lasting protection. It is available in ISO 32 through ISO 460 viscosity grades.
     
    APPLICATIONS
    Recommended for the lubrication of enclosed gears, mobile or stationary hydraulic systems and non-turbine circulating oils where an EP type of lubricant is not required. 

    Highly recommended for industrial equipment requiring R&O type oil such as electric motor bearings, blowers, pumps, compressors and machine tools. It is particularly recommended for lubrication on bronze on steel worm gears. 

    The lighter grade is for used in bearings and gears working under high speeds and low loads while the more viscous grades are for bearings, cranks and gears working under low speeds and high loads as well as for high pressure compressors.
