2019年1月3日 · Hydraulic oil (also known as hydraulic fluid) can be synthetic or mineral based. It’s a non-compressible fluid that is used to transfer power within hydraulic machinery and equipment. As a hydraulic oil supplier, we deal with 99% of mineral-based hydraulic oils.

Before you purchase a hydraulic fluid, make sure you have the right product for the job. Check out our chart and see what viscosity grade performs best at what temperature range.

The TOW chart can be used to identify the viscosity requirements for hydraulic equipment found in most climate-controlled manufacturing environments. These systems typically incorporate coolers and thermostats to stabilize the oil temperature.

Lines shown indicate oils ISO grade Viscosity Index of 100. Lower V.I. oils will have a steeper slope. Higher V.I. oils will have a flatter slope.

2024年12月7日 · Generally, hydraulic oil should operate within a temperature range of 150°F to 180°F (65°C to 82°C). Staying within this range helps maintain the viscosity and performance characteristics of the oil, ensuring robust hydraulic system functionality.

Choosing the appropriate viscosity grade requires considering factors such as system operating pressure, temperature, and speed. The Viscosity Index (VI) measures the change in hydraulic oil viscosity with temperature.

Hydraulic oil temperature range. Depending on the application of hydraulic fluid, it may be subject to cold or hot temperatures. In some cases, hydraulic oil can be subjected to both hot and cold temperatures which can render the oil useless if it hasn’t been blended with the right additives.

Allowable oil viscosity range on Oilgear pumps and Char-Lynn motors is 65-2000 SUS. To stay within the required viscos-ity range, use the recommended grade of hydraulic oil listed in the CLIMAX Hydraulic Power Units Oil and Temperature. chart below. Remember, the hydraulic oil will warm up during use, sometimes as much as 80 to 90 degrees F.

Viscosity of a hydraulic fluid depends on its composition and the temperature. Low viscosity limit is determined by the lubrication properties of the oil and its resistance to cavitation.

2024年11月5日 · The average hydraulic oil temperature when it begins to break down is around 140°F (60°C), and significant system damage occurs at around 180°F (82°C). It’s important to note that fluids come in different viscosities and operating temperature ranges. Check that your oil will work in your specific equipment and environment.
