Shell Omala S1 W 460
Shell Omala S1 W 460 is a high-quality mineral-based industrial gear oil formulated to provide reliable lubrication performance in enclosed worm gear systems and other low-speed industrial applications. Manufactured from carefully refined base oils and compounded with a small proportion of fatty oils, the lubricant is designed to deliver effective wear protection and stable performance in demanding operating conditions. The formulation is particularly suited to worm gear drives operating at low speeds and under heavy load conditions where consistent lubrication and dependable oil film strength are essential.
One of the key advantages of Shell Omala S1 W 460 is its ability to provide reliable wear protection in worm gear systems. Worm drives often operate at relatively low speeds and may experience heavy sliding contact between gear surfaces. Under these conditions it is essential that the lubricant forms a strong and stable oil film to prevent direct metal-to-metal contact. Shell Omala S1 W 460 helps maintain this protective lubricating film, reducing friction and wear while supporting smooth gear operation and extended equipment life.
Shell Omala S1 W 460 also offers good resistance to deposit formation during operation at elevated temperatures. Industrial gear systems and steam cylinders can operate under high thermal stress, which may cause some lubricants to form harmful carbonaceous or gummy deposits. The formulation of Shell Omala S1 W oils provides low volatility and natural resistance to deposit formation, helping maintain clean lubrication systems and consistent performance between maintenance intervals. This contributes to reduced maintenance requirements and improved reliability of industrial equipment.
Another important application for Shell Omala S1 W 460 is steam cylinder lubrication. Steam cylinders operating at high temperature and pressure require lubricants that can maintain film strength and resist thermal degradation. The formulation of Shell Omala S1 W 460 provides reliable lubrication performance under these demanding operating conditions, helping protect cylinder surfaces and maintain efficient equipment operation.
The lubricant is recommended for enclosed industrial worm gear systems, particularly those that may experience high levels of sliding friction or operate under stop-start conditions at low speeds. In these situations the oil helps reduce wear and control operating temperatures within the gear system. It can also be used for steam cylinder lubrication where high temperature and pressure conditions require a lubricant capable of maintaining film strength and stability.
Physical characteristics include a kinematic viscosity of approximately 460 mm²/s at 40°C and 31.2 mm²/s at 100°C with a viscosity index of approximately 98. The lubricant has a density of approximately 887 kg/m³ at 15°C, a flash point of approximately 318°C and a pour point of approximately –6°C, supporting reliable lubrication performance in demanding industrial gear and steam cylinder applications.
