Gear Oils
LubeCon offers a comprehensive range of Castrol gear oils to address varying needs and applications.
These Include:
- 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 range.
- Food grade gear oils, formulated from NSF International-approved lubricants
Gear Box Case Studies
Castrol products have routinely demonstrated improved surface performance in the field by arresting progressive wear problems in difficult, highly loaded gearbox conditions. Optigear 1100/460 stopped rapid micro-pitting wear of a dragline swing gearbox with severe load conditions and water contamination for a surface mining customer. In another case study, Optigear BM 460 extended the life of a gearbox that was expected to fail in six months (based on heavy wear and past history of failures) by over eight years for a major tire manufacturer.
