To increase productivity, many commercial operations rely on more frequent and prolonged high-load operation of commercial vehicles and equipment. The resulting thermal stress created in gear boxes can present challenges for the lubricant in the areas of performance, fuel economy and durability. Castrol gear lubricants are formulated to meet or exceed the highest industry standards so they can help you to overcome these real-world challenges.
We have engineered our gear oils to offer these performance benefits:
Castrol Alpha HC EP lubricants have been formulated with carefully chosen synthetic components for excellent performance in applications requiring AGMA (American Gear Manufacturers Association) EP gear oils.
This series of ISO grade, technically advanced chemistries excel in applications that require increased oxidation control and thermal stability, consistent anti-wear performance, and low carbon-forming tendencies. Synthetic components provide the potential for extended drain intervals and reduced maintenance costs.
The Castrol Alphasyn T range has been formulated for use in most types of light- to medium-duty enclosed gear systems, but should not be used for heavy or shock-loaded systems. These products are also suitable for bearings and circulatory systems operating at high temperatures, as well as for various applications where a lubricating oil is used under high temperatures, e.g. from hydraulic systems through to large, slow moving gears. All products in the Alphasyn T range have very low pour points and excellent viscosity and temperature characteristics, which allows their use in both low- and high-temperature applications.
Castrol AP Gear Lubricant is formulated with high-quality base oils and additives that provide excellent load-carrying ability, EP properties, wear resistance, oxidation stability and anti-rust, anti-corrosion and anti-foam properties.
These exceptional quality gear oils are designed for severe-duty applications and offer excellent gear protection. Formulated with selected base oils coupled with an extremely stable sulfur/phosphorous additive package, they are an ideal choice where AGMA EP gear oils are recommended.
This premium synthetic, heavy-duty, multi-grade gear lubricant meets API GL-5 service. It provides excellent cold weather performance, outstanding stability under higher than normal operating temperatures, and substantial load carrying ability for cooler operation and longer equipment life.
Our products and programs for heavy-duty vehicles are designed to meet the unique demands of all four key sectors: construction and landfill, mining and quarrying, refuse and vocational and on-road trucking. In every case, we are here to help ensure efficiency, reliability and productivity at all times.
In addition to a wealth of expertise and experience in heavy-duty vehicle segments, Castrol® offers a wide range of the products that you need to maintain productivity. These include: Engine Oils, Hydraulic Fluids, Driveline Fluids, Gear Lubricants, Greases and Coolants, all featuring liquid engineering to help keep your entire fleet running at peak efficiency.
Whatever kind of heavy-duty vehicles you operate, your profitability depends on performance and reliability. Our industry-leading Labcheck fluid-analysis program is predictive, not reactive. It can help you to identify problems before they turn into expensive breakdowns, and also help fleet managers to optimize drain intervals in order to reduce your total cost of ownership.
Castrol’s premium line of diesel engine oils combines exceptional base stocks and additive technologies that provide the performance and protection your heavy-duty equipment deserves. Find the right diesel engine oil for your heavy-duty equipment.
