What does sus mean for oil?
What does sus mean for oil?
Saybolt Universal Seconds
Saybolt Universal Seconds (SUS), which is the time in seconds for 60 milliliters of oil to flow through a standard orifice at a given temperature. This viscosity system is still in limited use, although it has been generally replaced by the ISO grading system.
Is ISO 32 hydraulic oil the same as AW 32?
AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celcius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.
What the difference between 32 and 46 hydraulic oil?
ISO 32 Hydraulic Oil – ISO VG 32 Hydraulic Fluid is ideal for use in high-powered machine tools. ISO 46 Hydraulic Oil – ISO VG 46 Hydraulic Fluid is normally required for industrial plant working under high-pressure etc.
What is SUS for hydraulic fluid?
Hydraulic oils thickness is specified by a SUS or SSU designation, similar to the SAE designation used for automotive fluids. SUS stands for Saybolt Universal Seconds (or as some put it, Saybolt Seconds Universal). It is a measuring system set up by a man named Saybolt.
What is the difference between SAE and ISO?
There is no significant difference between ISO (International Standards Organisation) or SAE (Society of Automotive Engineering). Both organisations provide test standards to allow the ability to reliably compare published filter ratings among manufacturers.
What kind of oil do you use in a hydraulic system?
5 gal. 1 gal. Use this oil in machines that require the same lubricant for both their hydraulic and way systems. Antiwear and oxidation-resistant additives make it work well with hydraulic systems, while moly gives it the high load-carrying ability required by way systems. Viscosity is the thickness of an oil.
What does 125 Sus at 100°F mean?
L.GSCF125/150, Golden Cartridge Fluid, light. “125” in the model description means 125 SUS @100°F. Containers may be marked “5” or Marzzochi
What kind of oil does a sx400 use?
O.SXSF SX400 Platinum Shock & Fork Oil, SAE 2.5W L.SFUL Ultralight shock fluid SSU 90? L.GSCF85/150, Golden Cartridge Fluid, very light. The “85” in the model description meant 85 SUS @100°F (16.9 Cst). Later containers may be marked as “7.5” L.GSCF125/150, Golden Cartridge Fluid, light. “125” in the model description means 125 SUS @100°F.
When to use phosphorus additive in hydraulic oil?
Use this oil where zinc compatibility or environmental issues are a concern. Phosphorus additives replace zinc to give it the wear-resistance hydraulic pumps and equipment need, even in high-pressure systems. Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows.
