Selection inputs for ISO VG 680 industrial gear oils, typically for very slow, heavily loaded gear sets where specified.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Viscosity Grade | ISO VG 680 (nominal kinematic viscosity at 40°C) |
| Operating Speed | Very slow operation; high viscosity can cause churning at higher speeds |
| Ambient Temperature | Cold flow may be limited; verify low-temperature requirements |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Correct Viscosity | Use only if OEM specifies ISO VG 680 |
| EP Performance | Often needed for high load, low speed gears |
| Foam/Air Release | Important for splash systems |
