Four Reasons To Choose Polyether Gear Lubricants

Polyether (PAG) is a high-performance synthetic base oil widely used in industrial lubricants due to its excellent viscosity-temperature characteristics, low-temperature performance, lubrication properties, and high-temperature cleanliness. Polyether synthetic industrial gear oils provide extremely low friction coefficients, effectively reducing equipment operating temperature and power consumption, thus achieving energy savings. They are particularly suitable for high-slip gears and various gear and worm gear drive systems under demanding operating conditions. Polyether synthetic industrial gear oils, formulated with polyether as the base oil, exhibit outstanding viscosity-temperature characteristics, extreme pressure anti-wear properties, and friction reduction capabilities, meeting the lubrication needs under high load and strong impact conditions. For example, elevator traction systems mostly use worm gear drives. The polyether worm gear oil formula uses a water-soluble copolymer of ethylene oxide/propylene oxide as the base oil, with a kinematic viscosity of 325.2 mm²/s at 40°C, a viscosity index of 241, and a pour point of -41°C.

Gear lubricants can be classified according to their base oil as follows:

Mineral oil type: Simply put, this is the most commonly used type, extracted from crude oil.

Synthetic oil type: Synthetic gear oil is mainly made from synthetic base oils or esters, and polyethers, as synthetic base oils, are widely used in lubricants.

Four Reasons to Choose Polyether Gear Lubricants:

1. High viscosity index and low pour point.

Different types of polyethers have varying viscosity-temperature characteristics, but their curves are smoother than those of mineral oils. The viscosity index gradually increases with increasing EO content. For example, Chorus's PAG-68 has a viscosity index of 160 and a pour point of -45℃; PAG-320 has a viscosity index of 239 and a pour point of -30℃.

2. Excellent lubrication performance.

At the same viscosity, polyethers have a lower friction coefficient than mineral oils. Their polarity and low viscosity-pressure coefficient allow them to form a stable and robust lubricating film under various lubrication conditions, resulting in low friction and shear resistance. Their lubricity is superior to mineral oils, polyalphaolefins, and diesters, but not as good as polyol esters and phosphate esters. The flexible and adjustable structure of polyethers allows them to be blended with other oils to meet a wide range of needs, giving them a unique advantage as a base oil in various fields such as gear oils and high- and low-temperature lubricants.

3. Good oxidation resistance.

Under oxygen-free conditions, they can be used up to approximately 250℃. They do not easily generate various oxides, reducing carbon deposits and sludge accumulation during combustion, protecting equipment from corrosion, and extending equipment lifespan.

4.Excellent heat dissipation.

They can quickly dissipate high-temperature heat under high gear loads, reducing temperature, thereby reducing friction loss, conserving energy, and improving energy efficiency.
