What do the numbers mean on hydraulic oil

The first number is the viscosity when the oil is cold. The number after the "W" is the viscosity after being warmed by the engine to operating temperature. Viscosity Scale

What do these numbers mean? In a nutshell, the numbers before and after the W represent viscosity. The letter “W” itself stands for Winter. As you may know, viscosity means the thickness of a fluid. In the case of motor oil, it is the thickness of the oil under certain temperature conditions. The number to the left of the W refers to the Re: Hydraulic Oil - what do the numbers mean? You have things backwards. Viscosity is the property of resistance to flow in a fluid so the higher the viscosity number the thicker/heavier the fluid. Also SAE stands for Society of Automotive Engineers and ISO stands for International Organization for Standardization. The first number is the viscosity when the oil is cold. The number after the "W" is the viscosity after being warmed by the engine to operating temperature. Viscosity Scale Monograde hydraulic oils are designated by one number (10, 20, 30, 40, etc.). The number indicates a level of the oil viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity. The actual ISO numbers correspond to the mid number of the minimum and maximum range of the ISO-VG. Based on the chart, the ISO-VG 32 is the midpoint of the ISO viscosity grade range of 28.8 to 35.2, and so on and so forth. What do the oil numbers 10W-30 mean? Your engines rotating parts are protected from heat and friction by a thin layer of oil. Understanding the viscosity ratings and detergents used in today's modern oils is critical to keeping your engine running. The number of boxes shown in the valve symbol is the number of positions for the valve. In the above symbol two square boxes are there so it is a two position valve. 2.

8 Oct 2012 Understanding ISO 4406 Cleanliness Codes is essential for fluid power need for good control of the fluids in our hydraulic and lubrication systems. so I asked, “Does anyone here want to know what those numbers mean? 30 Jul 2019 The hydraulic oil also travels through a filter that collects impurities. returns to its original position under the weight of the load (or by means of a manual lever). Refer to the valve packaging for further instructions and part numbers. A standard valve does not permit oil to escape as the cylinder retracts. Are you sure your current hydraulic fluid is doing enough for your equipment? This means that higher-quality fluids often can last well over 5,000 hours. codes, which will help explain the numbers associated with your particular fluid. When considering hydraulic oil, a question we often receive is "which is better, AW32 or AW46? AW means Anti-Wear. For Atlas above ground lifts, AW-32 ( lower number than AW-46) will flow "better" in colder weather than AW-46. We do not recommend the use of transmission fluid because its thinner viscosity (5W)   Dash Numbers, the industry standard, describe hose and coupling size.

Find the most common hydraulic terms and what they mean. Hydraulic Terms: A-C. ACCUMULATOR: A container which stores fluid under pressure. Used as an energy source or to absorb hydraulic shock. Common types are piston, bladder and diaphragm. BLEEDER (BLEED VALVE): A device for removal of pressurized fluid. Used to bleed air from system.
