roduct Description
Castrol ALPHASYN T150 is a premium ISO VG 150 fully synthetic PAO (polyalphaolefin) gear oil designed for high-temperature industrial gearboxes, bearings, circulating lubrication systems, hydraulic applications, and heavy-duty machinery requiring excellent thermal stability and extended oil life. This synthetic industrial lubricant provides outstanding oxidation resistance, high viscosity index, low-temperature performance, and reliable wear protection for enclosed gears, slow-speed machinery, and industrial equipment operating under demanding conditions.
Castrol ALPHASYN T150 is formulated using high-quality synthetic PAO base fluids combined with sulphur/phosphorus anti-wear technology to deliver excellent load-carrying capability, reduced friction, and improved equipment protection compared with conventional mineral oils. The product is suitable for light to medium-duty enclosed gear systems, high-temperature bearing lubrication, and circulating oil applications where long lubricant life and wide operating temperature capability are required.
