What is the difference between AW 46 and AW 68?
What is the difference between AW 46 and AW 68?
ISO 46 Hydraulic Oil – ISO VG 46 Hydraulic Fluid is normally required for industrial plant working under high-pressure etc. ISO 68 Hydraulic Oil – ISO VG 68 Hydraulic Fluid is designed for use in systems which require a large load-carrying ability.
Which oil is thicker 32 or 68?
32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.
What does ISO stand for in oil?
International Standards Organization Viscosity Grade
ISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. This number is critical because a lubricant’s viscosity is the single most important factor when selecting the right oil for your machinery.
Is ISO and aw the same?
The ISO classification for these oils is HL. AW stands for anti-wear – R&O oils with an anti-wear additive package. The ISO classification for these oils is HM. The ISO classification is HR for VI-improved R&O oils and HV for VI-improved AW oils.
Is ISO VG 46 the same as AW 46?
AW 46 Hydraulic Oils contain a zinc anti-wear additive that is designed to protect hydraulic systems and equipment by reducing wear. AW 46 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 46. This is the thickness of the fluid tested at 40 degrees Celsius.
What is ISO 32 oil?
Hydraulic 32 is part of Crown Oil’s range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.
What does ISO 32 mean?
Instead of being rated using the SAE scale, they’re measured under the ISO scale. ISO grades measure viscosity at 104°F(40°C). When you look at, for instance, ISO 32 hydraulic oil it will flow much more quickly than ISO 68 hydraulic oil. Different viscosities are better for different applications in the field.
