Castrol Optigear BM 680
Castrol Optigear BM 680 is a high-performance extreme pressure gear oil, developed to tackle wear-related problems in heavily loaded industrial gears and bearings. Optigear BM 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.
