Gear Oils
LubeCon offers a comprehensive range of Castrol gear oils to address varying needs and applications.
Our range of Castrol gear oils includes:
- Mineral-based gear oils are derived from highly refined base stocks and blended with a variety of additives such as corrosion inhibitors, anti-foam, anti-wear, and anti-scuff/extreme pressure compounds.
- Synthetic gear oils are specially engineered to handle extreme conditions with enhanced features such as thermal stability, high load carrying capacity, extreme pressure, high viscosity index, and wide temperature scope.
- Food grade gear oils, formulated from NSF International-approved lubricants.
Gear Box Case Studies
Castrol gear oils have routinely demonstrated improved surface performance in the field by arresting progressive wear problems in difficult, highly loaded gearbox conditions. Some of these situations include:
- Mining Industry Success: Optigear 1100/460 Castrol gear oil stopped rapid micro-pitting wear in a dragline swing gearbox operating under severe load conditions and water contamination.
- Tire Manufacturing Triumph: Optigear BM 460 Castrol gear oil extended the life of a gearbox from an expected 6-month failure to over 8 years of continuous operation.
