Castrol Optigear Synthetic™ 1710 (previously called Tribol 1710) is a range of high-performance extreme pressure gear oils, developed to help tackle wear-related problems in heavily loaded industrial gears and bearings. Optigear Synthetic 1710 is formulated with Castrol's Tribol Gear Oil Additive (TGOA) Plastic Deformation (PD) additive and high quality mineral base oils and synthetic polyalphaolefins. TGOA 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 delivers optimum wear protection and an extremely low coefficient of friction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds. TGOA 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.
