What is the Castrol Optigear range?

The Castrol Optigear range is a selection of high-quality gear oils that use advanced technology to deliver high performance. The products included in the range are engineered with MicrofluxTrans Plastic Deformation (MFT-PD) technology to create next-generation gear oils with advanced capabilities.

Understanding gear oils

Gear oil is a type of lubricant that is made specifically for use in the transfer cases, transmissions and differentials found in trucks and automobiles, among other types of machinery. Gear oil usually has high viscosity and formulas typically includes organosulfur compounds. There are some current automatic transaxles that don’t use heavy oils at all, instead lubricating using the lower-viscosity product known as hydraulic fluid, an option available at pressure in an automatic transmission. Current figures show that gear oils make up around 20 per cent of the products on today’s lubricant market.

The vast majority of lubricants designed for manual-type differentials and gearboxes include additives developed to offer extreme pressure (EP) and anti-wear properties to handle the sliding action associated with hypoid bevel gears. Common inclusions are organic compounds that have been treated with sulphur and dithiocarbamate derivatives.

Optimising efficiency with low-friction gear oils

Castrol developed its Optigear range to answer the challenges of modern markets seeking enhanced gearbox efficiency for their operations. A high level of gearbox efficiency is a driving force in organisational success for many competitive industries, such as automotive, manufacturing and wind power.

The main challenge faced by operations is friction, due to the fact that it can compromise gearbox efficiency. Optimising the efficiency levels of any gearbox will always depend on how effectively friction is controlled. Friction in gearboxes generates extreme heat, and this increase in temperature puts thermal stress on a system’s components. As a result, pitting and wear can occur. These negative effects can shorten the lifespan of machine parts, eventually reduce performance in gearboxes and cause unscheduled downtime, not to mention labour and component replacement costs.

Actively lowering friction levels with Castrol Optigear

Working under increasingly greater loads, Castrol’s MFT technology is deployed, producing a micro-smoothing impact that enhances the quality of all gear surfaces. Statistics show that Castrol Optigear has a proven record of lowering friction coefficients by as much as 60 per cent compared to conventional gear oils, and it actively resists pitting and wear.

Lower friction levels lead to lower operating temperatures for gearboxes and a greater defence against pitting and wear. Castrol Optigear oils improve the performance of gears, ensuring gearboxes run more efficiently, making businesses more productive.

Gear oils for industrial applications

Castrol’s Optigear Synthetic PD ES products are high-performance, solid-free gear oils that are Flender-approved. They are designed to deliver dependable long-term lubrication for gears used in industrial machinery and to work in extreme heat and cold and with heavy loads.

Whether for bevel, heavy-loaded, spur or planetary gears, this range of synthetic gear oils can help minimise abrasion and equalise surface roughness, improving surface profiles of contacting gears. It can also reduce energy consumption and drain intervals by providing enhanced surface protection and lowering friction by 30 per cent.
