CASTROL Optigear Synthetic RO 150

Industrial Gear Oils

Optigear Synthetic RO 150 is a high-performance synthetic gear oil for gears used in rail traffic and mechanical engineering applications such as in robots. The properties of Optigear Synthetic RO 150 mean it can be used in extreme climate conditions and for long-term use.

Optigear Synthetic RO 150 can be used for all types of spur gear teeth, even under difficult load conditions. This include bevel gear units, also with a large offset (hypoid) and heavy alternating loads; and all types of roller bearings, with heavy loads on wide range of temperatures up to +93 °C.
Does not recommended for synchronised gears or limited slip differentials due to low friction coefficients.

RO 150 can be used for dip lubrication at high numbers of revolutions, as well as injection and oil mist lubrication.

Optigear Synthetic RO is formulated with Castrol's Microflux Trans (MFT) Plastic Deformation (PD) additive. MFT PD helps improve performance when operating temperature and loads reach a certain level of activation energy, by enabling the micro-smoothing of surface roughness without increasing wear. The smoothed surface delivers optimum wear protection and an extremely low coefficient of friction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds. MFT PD helps to protect against scuffing and shock loading, while maintaining a high load carrying capacity, and can help prevent the progression of micro-pitting in pre-damaged gears.
