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 cold weather grade is recommended for ambient temperatures ranging from -40°F (-40°C) to 50°F (10°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 harsh, cold environments
