Mineral oil based industrial gearbox oil
MB Gear is a premium gear oil designed for the lubrication of open and closed gears working under heavy conditions and/or shock loads. Excellent wear protection under extreme pressures/shock loads. High thermal and oxidation stability allowing continuous use at elevated temperatures. Effective protection against rust and corrosion. Very good anti-foam properties as well as water separation characteristics. MB Gear is also compatible with yellow metals in worm gears, but for that application we recommend Geartop PAG.
