Anti-wear hydraulic fluids No. 46 and No. 68 are two different types of hydraulic fluids that differ mainly in their viscosity and high-temperature properties. No. 46 hydraulic fluid has a lower viscosity and is suitable for use in lower temperature and light load working environments, while No. 68 hydraulic oil has a higher viscosity and better high temperature performance, making it suitable for use in high temperature and heavy duty working environments.
In addition, No. 68 hydraulic fluid also has better oxidation and thermal stability, which can better protect the metal parts in the hydraulic system from oxidation and corrosion. At the same time, No. 68 hydraulic oil also has better anti-foaming and air release, which can better ensure the stability and reliability of the hydraulic system.
When choosing a hydraulic oil, you need to choose it according to the specific working environment and equipment requirements. If the working environment temperature is low and the load is light, you can choose No. 46 hydraulic oil; If the working environment temperature is high and the load is heavy, you need to choose 68 gauge hydraulic oil.
In conclusion, the main difference between No. 46 and No. 68 hydraulic fluids is their viscosity and high-temperature properties, which need to be selected according to the specific working environment and equipment requirements.
