9/11/2023 0 Comments Oil viscosity chart in fahrenheit![]() The fluid film needs to be thick enough at operating temperature to separate the two surfaces even under load however, they should not be so thick that the parts have difficulty moving due to the viscous lubricant. It’s these asperities that will come into contact as metal parts slide unless there’s a proper fluid film at operating temperature. How Temperature Impacts Wear ProtectionĪlthough two metal surfaces that come into contact in a machine may look extremely smooth, magnification of the surfaces would reveal a scene that more closely resembles a mountain range with mountain tops (asperities) and valleys. The lower the viscosity index, the more the viscosity is impacted by changes in temperature. A viscosity index (VI) is assigned to a specific lubricant so that users have a clear understanding of the viscosity state at varying temperatures. As lubricants get hot, their viscosity drops as they get cold, their viscosity increases. A lubricant’s viscosity will change with changes in temperature. If it’s too thin (like water) and moves too freely or quickly, it does not form a sufficient film to separate moving parts, wearing out machines more quickly. If the lubricant is too thick, it flows more slowly (like molasses), creating more friction and thus negatively impacting the efficiency of equipment. Viscosity is the single most important performance property of a lubricant. How Viscosity and the Viscosity Index Work for You ![]() So, let’s start at the critical role viscosity plays when selecting the right lubricant and how changes in temperature require careful consideration when applying these lubricants to a single machine, at one site, or across a global enterprise. It is important to understand how a zubricant’s resistance to flow (the viscosity)-and its impact on product selection-is more than operationally smart, it’s bottom-line savvy.
