Servo Hydraulic Oil 121 is a premium-grade anti-wear circulating and hydraulic oil formulated for efficient lubrication of systems operating under high mechanical stress and temperature. Developed with refined base oils and advanced oxidation inhibitors, this oil ensures long-lasting protection and superior film strength across a wide range of industrial applications. Its balanced additive composition provides reliable performance in continuous circulation systems, offering excellent resistance to oxidation, rust, and corrosion, which are critical in maintaining system cleanliness and extending equipment life. With a kinematic viscosity range of 118–124 cSt at 40°C and a flash point of 220°C, Servo Hydraulic Oil 121 guarantees consistent lubrication, minimizing frictional losses even under heavy load conditions. The oil’s high viscosity index of 90 ensures stable performance under varying temperature conditions, while its excellent demulsibility allows for effective separation of water and contaminants, preventing operational downtime. Designed for industrial circulation and hydraulic systems, Servo Hydraulic Oil 121 is particularly recommended for use in paper mills, plastic film calenders, coal pulverisers, compressors, and machine tools where sustained performance and reliability are essential. It performs exceptionally well in enclosed gearboxes and bearings that do not require EP (Extreme Pressure) type lubricants, ensuring smooth operation and extended component durability.
