United Fully-Syn industrial Gear & Bearing Oil are formulated with proprietary synthetic polyalphaolefin (PAO) base and ester technology with performance additives that enhance oxidation stability, improve foam control, maintain superior stability in the presence of water, and provide protection against rust, corrosion, and wear. Synthetic base oils provide longer oil life than conventional mineral oils.

United Fully-Syn industrial Gear & Bearing Oil has a naturally high viscosity index (VI) compared to mineral oils, providing lower viscosity at lower temperatures and higher viscosity at higher temperatures. This high VI allows the oil to flow at cold temperatures so equipment will start. It also means viscosity will be maintained at high temperatures to provide wear protection.
