Technical Field

Aiming at the working characteristics of the open gear, the open gear lubricating oil is required to have good adhesiveness, high wear resistance and strong extreme pressure resistance, can provide enough oil film strength for the open gear, and ensures the normal lubrication of the gear.
Open gear lubricants were primarily pitch-type and solvent-diluted lubricants in the early stages of development, but such lubricants have been phased out by the market because they are environmentally friendly and harmful to humans.

Among them, the synthetic open gear oil has excellent oxidation resistance, good adhesiveness and low-temperature fluidity, and transparent appearance, and easy observation of the lubrication state of the equipment, but the occupancy rate in the market is relatively small due to relatively high cost.
