Castrol Optigear Synthetic X Range

Castrol Optigear Synthetic X Range

Product description

Castrol Optigear™ Synthetic X is based on synthetic hydrocarbons and Castrol's Microflux Trans (MFT) Plastic Deformation (PD) additive and surface improvement additive package.

MFT PD helps improve lubricant 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 deliver soptimum 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.


Optigear Synthetic X has the following advantages when compared to product in a similar class:-

- High load carrying capacity.

- Superior micro pitting protection.

- Excellent friction reduction.

- Good filtration properties.

- Excellent bearing lubrication suitability.


Optigear Synthetic X may be used in spur gear, bevel gears or planetary gear units and in heavy loaded gear units, e.g.wind turbine main gears. It is also suitable for the lubrication of oil-lubricated rolling bearings.Depending on the specific application, Optigear Synthetic X may be used in an operating temperature range from -30°C/-22°F to +100°C/212°F (refer to a Castrol technician for more information, if necessary).Optigear Synthetic X is a CLP-HC gear oil (according to DIN 51502) and exceeds the minimum requirements accordingto DIN 51517 (2003), part 3, CLP gear oils, tested on the ISO viscosity class 320.
