Cat® Open Gear Lubricant is a high-viscosity semi-synthetic compound designed to protect heavily loaded open gears while extending component life and reducing lubricant consumption. The warm weather grade is recommended for ambient temperatures ranging from 20°F (-7°C) to 120°F (49°C). It delivers exceptional performance in high-load conditions, thanks to solid anti-wear and extreme pressure additives that provide superior protection in the most heavily stressed areas of gear tooth mesh. Its formulation also resists wash-off in wet conditions, making it ideal for use in rain-exposed environments
