Castrol Optigear Synthetic 1710/320

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.

Castrol Optigear Synthetic 1710/320 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.

Typical applications are in spur, helical, herringbone, bevel and planetary gears as well as in geared couplings, rolling and sliding bearings and in gear drive circulating systems.

Depending on the application, Optigear Synthetic 1710 may be used in a temperature range from –30°C up to +95°C / – 22°F up to 203°F (please contact your Castrol Technical Services team for further information).

Optigear Synthetic 1710 semi-synthetic gear oils are compatible with most mineral oils, ester and synthetic-based products. This means that traces of up to 3% of previous oil in the gear case after draining will not pose any problems. However, the beneficial effects of the TGOA additives are reduced when Optigear Synthetic 1710 oils are mixed with other gear oils. Optigear Synthetic 1710 oils are not compatible with polyglycols. After draining a polyglycol fill, the gear case must be flushed well with mineral oil or flushing oil.

Optigear Synthetic are CLP-HC gear oils (DIN 51502) and exceed minimum requirements according to DIN 51517 T.3
for ISO 320 and 460 grades

Compared to conventional gear oils (of similar class), Optigear Syntehic 1710 provides the following advantages:

• High load carrying capacity as demonstrated in Load stage >12 being passed in the FZG test (for ISO 320 and above)
• Excellent wear prevention as demonstrated in the FZG micro pitting test (for ISO 220 and above)
• Running-in pitting is prevented or stopped unless caused by poor design or heavy overloading of the gears
• Lapping of gears is no longer necessary
• Previous pitting or damaged surfaces can be stopped or visibly reduced
• Lower operating temperature and noise level
• Extended service life of gears and bearings, which helps to reduce maintenance costs
• A high viscosity index allows start-ups at low temperatures due to the lower viscosity and allows the build-up of a lubricant film with sufficient thickness at high temperatures

This product was previously called Tribol 1710. The name was changed in 2015.
