十堰郧西县竹山县壳牌导轨油-齿轮油供应链The core parameters of 320 gear oil revolve around viscosity and extreme pressure performance, with specific values varying depending on the type of base oil (mineral or synthetic).

　　Viscosity characteristics:

　　40 ℃ kinematic viscosity: The standard value is 320mm ²/s (cSt), ensuring sufficient oil film thickness is formed at a specific temperature.

　　Viscosity index: Mineral oil is usually around 96, while fully synthetic oil can reach over 160. A high viscosity index means better low-temperature fluidity and high-temperature lubricity

　　320 号齿轮油的核心参数围绕粘度及极压性能展开，具体数值因基础油类型（矿物或合成）而异。

　　‌粘度特性‌:

　　‌40℃运动粘度‌:标准值为 320mm²/s（cSt），确保在特定温度下形成足够的油膜厚度 。

　　‌粘度指数‌:矿物油通常在 96 左右，全合成油可达 160 以上，高粘度指数意味着更好的低温流动性和高温润滑性
