Greyhound Synthetic Gear 320 1L
Greyhound Synthetic Gear 320 (SH4 320) is formulated with a high-quality PAO (polyalphaolefin) base, designed to deliver superior lubrication for heavily loaded mechanical gearboxes and bearings. Specifically, this 1L synthetic oil offers longer oil-drain intervals, making it ideal for high-demand industrial environments where reliability and efficiency are critical.
Because the PAO base provides exceptional thermal stability and oxidation resistance, this oil reduces degradation and extends service life. Moreover, it carries anti-wear and extreme-pressure additives, so gears and bearings stay protected under heavy load and high temperature.
PAO Synthetic EP Gear Protection
For example, it performs reliably at high temperatures and resists oil breakdown across long service cycles. In addition, it is fully compatible with standard seal materials and paints, making it an excellent replacement for mineral-based gear oils. As a result, equipment runs smoothly and downtime falls. Therefore, plant operators reduce maintenance costs while protecting heavily loaded gear systems. Furthermore, the SH4 series meets the most rigorous extreme-pressure standards and is comparable to SHC synthetic hydrocarbon gear oils, so it suits the toughest industrial duty with confidence.
